This is a good review of the history of companies taking from open source and not giving back, Ploum has a good overview.
It's also a reminder of Meta getting involved in some sort of new project, and they're doing what large companies have always done, steal from open source and open protocols. They then either create or join some "open protocol foundation", stack the meetings with their engineers, co-opt the protocol and eventually give up when they can't make enough money off being "open" .
Those wise to these schemes have already started a pact to not connect to Meta's rumored instances. I hope the pact survives whatever Meta unleashes.
There are far, far more examples of this situation from trillion dollar businesses.
