Well that and the story while not "wrong", is definitely hyperbolic. The author even stated after stating that Google killed XMPP that they didn't. So which is it? I'm not a dev, but an avid open source fan. i first tried Linux in 1995. Started using jabber itself in 1999 through Gaim. Later pidgin and psi clients in 2001-2. There were a ton of problems beyond Google. As far as clients were concerned there was no reference version. And there really were no large professionally run servers like mastodon.social or lemmy.world. People, myself included put too much hope in the Google basket. It was a massive unearned win in user count. That was just as easily lost. And kept people from focusing on the core service. Yes Google was never a good steward. Corporations never are. But the lack of official clients and servers, plus their decision to persue IETF standardization had as big or bigger impact on the services development and adoption.

The moral of the story isn't that Google or anyone else can kill an open source project. Microsoft Google and many more have tried and failed. The moral is that we shouldn't cater to them or give them special treatment. They aren't the key to success.
