If they bought RH or Canonical at least we would have one less vendor to add to the fragmentation. At least in my eyes, the moment something like this happens it would be like a black hole vanished with that entire "distro" ecosystem.
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.
