Without the ideology there would be no open source. It's like saying you can have churches without religion. You take the religion away, you'll still have the building but it's a matter of time before they're gone.
I am speaking of both FOSS and open source. As I said earlier these environments only exist so long as business can profit from it. This is because like you said the heart of what created the environments is gone. When business has a new model, like building what open source can with AI, then it'll die out too. There's a reason the more business friendly one is thriving.
That's what happens when generations ignore their roots
