@hcf @dans_root @earthnewstech @monocles You don't get #SelfCustody of all the keys on their platforms, to the point that #ProtonMail bricks #LKML useage!

  • If you had actual Self-Custody, then it would be real #E2EE and not a mere "#TrustMeBro!"-Security

Please go to a #CryptoParty and learn abdolute fundamentals re: #Cryptography, #InfoSec, #OpSec & #ComSec.

@hcf that's just wrong and you know that.

For example, if "#Security" was a real issue, they'd host their #IMAP+#SMTP access exclusively over @torproject / #Tor because #OnionServices are using fully-encrypted connections in a self-authenticating adress spaces.

  • They don't because that isn't the issue, and I'm not talking about the Server-to-Server - Connectivity, which is INHERENTLY AND UNFIXABLE INSECURE WITH EVERY EMAIL PROVIDER unless they don't allow actual cross-provider eMails (or restrict it to very few, selected competitiors with spechally negotiated connectivity [i.e. #VPN|s], which to my knowledge NONE of the commercial providers do)…

I brought up @monocles because they at least don't lie to customers and are honest about security & privacy!

@hcf @dans_root @earthnewstech if you don't understand the concept of "#Self-Custody" of Keys then you ain't in the position to be angry.

I merely hinted at the fact that @monocles isn't making false security promises and instead encourages proper #OpSec, #InfoSec, #ComSec & #ITsec practises…

@lackthereof no, it's not because unlike #Phones and #PhoneNumbers, #eMail is not necessarily traceable by circumstances.

  • Because a Phone "Line" (regardless of whether it's POTS, ISDN, VoIP, GSM, VoLTE, …) and #telephony in general are designed for realtime communication, they inherently necessitate an active, ongoing connection.
    • Even if it's just some App/PBX/… to connect to the provider and constantly state "I am on the network and able to recieve calls!" (with PSTN networks, there a physical line that gets assumed to have a phone connected)…

Whereas with eMail (and any #asynchronous #communication) you don't have that requirement.

  • So unless the provider is being taken over or otherwise "cooperative" there's no means for a sender to know where, when and how a message was retrieved unless the recipient wants the sender to know of it!

Or to put it simple:

  • You can ring up someone and thus circumstantially verify the chain of #PhoneNumber -> #IMSI -> #ICCID -> #SIM -> #IMEI -> Device -> Location -> Owner quite quickly.
    • Whereas you can't positively verify whether an eMail address and/or #XMPP+#OMEMO account belongs to me unless I want you to know that it does!

So either way a phone number is just a horrible means of doing that.

  • And don't even get me started on the fact that legally speaking noone truly owns their number.
    • Because even if you got some spechal case number (like UPT was) you still depend on neither regulators nor telcos to not block or otherwise interfere with it. Which is in contrast to say an OnionService which can only be shutdown effectively by sabotage aka. (more or less figurately) "unplugging" it.

I mean, it's not as if I didn't gave @signalapp a fair chance.

  • I wanted #Signal to be good - honestly...
    • But I'm old enough that things rarely are that simple as #TechPopulism & #Propaganda claim it to be.
    • Just like 5th grade #SexEd is not a substitute for Endocrinology, Gynecology and Andrology and actually licensed, medical professionals.

So any #Messenger service that requires a #Phone Number for signup and/or useage is truly not a real replacement and inherently makes PROVEN WRONG assumptions [i.e. that it is legal and possible to obtain a phone number anonymously at someone's juristiction] about it's customers' ability to shield their privacy

THIS is why I am going fucking ballistic on #TechPopulism aiming at #TechIlliterates because it's spreading a "false sense of #security" whilst completely disregarding absolute fundamentals when it comes to the underlying systems.

@kkarhan @GrapheneOS @tails_live @torproject @signalapp

"GrapheneOS chose their requirements and they can happily design their own platform instead."

There's no need to reinvent the wheel. AOSP is a secure, open-source platform that has been around for almost 20 years. I don't want to debate rumors that Google wants to make AOSP proprietary because there is no evidence to support this, especially since it would not benefit them in any way.

"I just think that their stubbornness"

It's not stubborness and I explained why.

"They are the antithesis to #Tails when it comes to #UserFriendly-ness and approachability for #Normies and #TechIlliterates

It's probably the first time I've seen “Tails” and “Normie” in the same sentence, It's not that Tails is difficult to use, but I'm really not sure that many “normies” use it or even know it exists. The user experience on GrapheneOS is almost identical to Pixel OS, the standard operating system for Google Pixel devices, so using GrapheneOS is likely to seem much simpler and familiar to normies, as they will already be used to it.

"Espechally since the problems woth #MobilePhones and the underlying technology ain't fixable with an #AndroidROM

GrapheneOS is not a ROM, Pixel OS is not a ROM, and LineageOS is not a ROM either, theses operating systems are not ROMs.

"Instead we need to foster a #SecurityCulture and proper #ITsec, #InfoSec, #OpSec & #comsec

Indeed, and what GrapheneOS does about security is completely appropriate, including informing people and giving them good advice.

"Otherwise we'll see them fail the same way @signalapp did, which is eitger getting shut down (#EncroChat-style) or being uncovered as a controlled opposition / honeypot (like #ANØM aka. #OperationIronside aka. #OperationTrøjanShield)…"

Signal did not fail, and mentioning Encrochat, ANON, and honeypots in the same sentence is irrelevant. These things have absolutely nothing in common with Signal, you seem to be believing made-up stories.

@Xtreix well, @GrapheneOS chose their requirements and they can happily design their own platform instead.

  • I just think that their stubbornness makes them look like Stallmanist extremists to the point of being unbearable cringe and completely loosing the plot.

To the point that it's cheaper to go black/red and teach that to people, even at the risk of inconvenience.

  • I mean, in many juristictions one will have to do so anyway, but that's not tue point here…

I think #GrapheneOS prefer to "die on their hill" of "moral superiority" than fave the reality that 99% of people can't and won't blow $500 - $1000+ on a phone when any half-decent Netbook with @tails_live , @torproject and #4G or #5G modem can do the same.

Otherwise we'll see them fail the same way @signalapp did, which is eitger getting shut down (#EncroChat-style) or being uncovered as a controlled opposition / honeypot (like #ANØM aka. #OperationIronside aka. #OperationTrøjanShield)…

@humanhorseshoes IDK Russian but I'd not be surprised if #Roskomnadzor is putting out something like it but trying to get parents to snitch on #LGBTQIA* #children!

As for #Russia, they don't give a fuck as long as the #victims are from #overseas (see #CONTI) and the perpertrators ain't behind on their Protection Money (see #rEvil)...

  • #Cybercrime is the only industry consistently growing in Russia since the late 1980s.
    • And #Putin certainly won't change that.

Still the #UK isn't new to such shite...
