@abhibeckert@dark_stang where are you getting all of this from?! Apps run in the background all the time, and there were mobile XMPP clients around back in the day. Pretty sure even Skype did XMPP for a bit.
@Dee_Imaginarium@giallo I wish most Mastodon instances were planning to defederate from Meta by default but sadly that's not the case. Meta reached out to the admins of some of the big instances and a whole bunch of them don't plan to. One of the admins shared this — https://fosstodon.org/@kev/110592625692688836
Some admins are going for a "trust but verify" approach. These are the only instances which have agreed to defederate from the start —https://fedipact.online/
