@jscalzi : please stop using a http links if websites support https.

By specifying vote.org (or vote.org/ which gives the same result) in a link, or by typing vote.org in the address bar of your browser, there are three possibilities:

1) the browser connects to the _real_ vote.org website;

2) the browser displays a certificate error (never continue in such a case);

3) extemely unlikely (see [1]): the browser connects to a fake website that managed to obtain a valid certificate for the vote.org domain name.

(Note: I used the Unicode '/' character instead of the regular slash char '/' to prevent Mastodon from hiding the protocol).

By default, _none_ of the popular web browsers prevents active (i.e. not passive) criminals from successfully conducting Man-in-the-Middle attacks - if the first connection-attempt uses http.

Most browsers _may_ TRY https first, but an attacker can block that request, forcing the browser to downgrade to http (if the user explicitly requested https, such a downgrade to http will _not_ happen).

Such attacks can be conducted in various ways, such as by using an "evil twin" WiFi access point (bleepingcomputer.com/news/secu) or by manipulating DNS replies to browsers.

Note: the domain "vote.org" is currently _not_ listed in the HSTS preload list (apparently it was removed because of stupidities): hstspreload.org/?domain=vote.o (being listed would _force_ browsers to use https, even if "the user" requested http by tapping on such a link).

See also the unnecessarily poor results in internet.nl/site/vote.org/2883

Unfortunately also @BleepingComputer regularly uses unnecessary http links in their articles.
