People on here bemoan the loss of XMPP integration and federated access to these platforms, but do Facebook/Google/Microsoft really give that much of a shit about that? I suspect the % of their userbase who wants, let alone understands those features is very small
Of course they don't give a shit. Because they understand the game - they're the ones putting things on the market, and users have zero choice (network effect means good marketing beats any feature set here).
