Why is this being downvoted? Isn't that what Google did? Started using XMPP openly, then locked it down over time and made it harder for people outside their ecosystem?
Yeah. Google was using XMPP but development focus was for Google Chat only. The rest of the community played catch up while Google chat got new features quickly. If you were using some other software, chat would simply break and crash.
The good old Google way. I’ve no idea why so many people are so willing to hand over everything to them. Say what you like about Apple, but at least they’re not selling your personal info.
XMPP was never Google only, it always had free implementations of both client and server while having community using it outside of Google.
While RCS is really not possible to use now without Google.
