Are you trying to claim that something like React/React Native/Jest weren't mostly done by Meta, but by the open source community, and Meta was just riding the coattails of their free work? You count VSCode to be in the same category as well (swap Meta for Microsoft instead)?

That's quite a claim, and I dont believe it is substantiated.

No, I'm saying any benefit by open sourcing it vs. just keeping it in house (the difference) would be free labor. Not the entire project of course!
