I sort of think the spirit of open source is on life support

Building giant monopolies on top of open source code wasn't in the spirit of open source either. Training AI that reproduces open source code without any credits wasn't either.

I'm not sure why people working on Open Source should continue to accept being whipped like that

It's the philosophy of sharing flames among candles. someone else copying the flame does not make you colder. No matter how much brighter another candle burns.

But with that said: I think it's time we figure out how to exclude the metaphorical arsonists.
