Early on when Google wasn’t shit and Facebook was just coming out of the startup phase both of them had chat platforms based on XMPP (the OG federating protocol). For a few glorious moments everyone could chat with anyone through the corresponding XMPP endpoints. At some point they decided they can’t be arsed anymore and shut off federation on their servers. They captured enough market and siloed their users.
There’s 1 million % this will happen again. It’s textbook EEE.
Well done on Mastodon admins for not cooperating with Facebook’s strong arming tactics. Facebook’s server will evolve into another walled garden, Mastodon federating with them will only help them.
Fuck them
Yes Conversations is still a paid app on Play Store. The F-Droid version also doesn’t support Google cloud notifications so some message notifications will go missing occasionally. For Android there’s also Quickly which is a Conversations fork and aTalk which works OK but reminds me of 90s Windows software. It’s still quite usable though. Honestly Conversations is totally worth the money if only for the amount of effort gone into modernising the platform which also a testament to its extensibility.
