Well then. Looks like @protonmail deleted the "we don't log your IP" claim from their website now:
@jamesrichardson It's ... honest.
More honest would be "we minimise data collection but will have to comply with any lawful data requests". That's what virtually any provider will have to do.
Keep in mind that Mastodon makes promises of a similar nature in its own branding and promotion which it cannot possibly assure and most of which are flagrantly untrue.
(I use, obviously, Mastodon, and perhaps somewhat less obviously, Protonmail.)
This Mastodon instance is for people interested in technology. Discussions aren't limited to technology, because tech folks shouldn't be limited to technology either!
