But when Steam started to develop Proton, WINE was 90% there! Valve only had to provide the remaining 90%.
The strength of Linux and Free software in general is not in that it's completely built by unpaid labor. It's built by a lot of paid, full-time labor. But the results are shared with everyone. The strength of Free software is that it fosters and enforces cooperation of all interested parties, and provides a guarantee that defection is an unprofitable move.
This is one of the reasons you see Linux everywhere, and *BSD, rarely.

I doubt it's a large reason. I'd put more weight on eg Linus being a great project lead and he happens to work on Linux. And a lot of other historical contingencies.
BSD does a few things right, hence it's used by Netflix (who share back some of their work), userland of macOS (because Apple don't like GPL, I assume), PS4 and PS5 (IDK if anything seeps back upstream from there).
