"we can benefit from the improvements that others make and others’ use of those tools can"

I have always had the impression that maintaining an open source project is way more work than you get back from "the community" of users. Is this not true? Are for instance the internal facebook react users benefiting a huge amount from what outside contributes have built on top of react?

I think an unspoken dimension is that kneecaping the other big tech companies' entrenchments and denying them a market is always good for them - esp when as they point out, it doesn't actually hurt any of their own business interests. Other faang are always a future threat. Hurting them is always a good business move
