What do you mean? I don't see how that can happen. Maybe a few "power moves" here and there, and companies already poach OS devs anyway. There's also licenses, CLAs.

Worst-case scenario people would just rewrite parts of the stack to move around it. There's people salivating at this very moment just thinking about rewritting core stuff in Go, Rust, or something else, and making a blog post about it. Imagine if they had an actual motive to do it.
