Matrix? E2E isn't even enabled by default anywhere, the server uses a ridiculous amount of resources, alternative servers support half of the protocol, I cannot easily discover people I know from my contacts lists via mail/phone/address/ICQ number/etc, 70% of the bridges I would need hover between "barely functional" and "the compiler isn't complaining", guilds are not easily possible as in other chat applications and their clients draw more battery than any other chat program I tried, including Skype, which I think qualifies for an achievement award of some kind. I think I'll stick with services that offer E2E and/or sensible feature-sets. Once Matrix fixes all their problems I'll gladly install a homeserver and run it open for other users to sign up for, until then I'm on Signal.
