@signalapp Signal IMO has bad security because when someone decides they are not interested in an overpriced, underperforming service of "phone number" and stops using their SIM, they cannot deregister the number from Signal and the new owner of the number either can hijack their Signal account, or people may be blocked from using newly purchased SIMs with Signal.
Also, authoritarian regimes IMO can temporarily transfer a number into a provider's internal SIM in order to hijack a Signal account and impersonate a dissident against another dissident, facilitating abduction, torture and murder.
I feel
c o n t e m p t
towards Signal when it is designed this way.
