You can't have it all, forever -- the tech is there for anyone to fork and improve, build new businesses (!), inspect, etc. F/OSS is basically a miracle as-is.

If we compare the current state of the world to one in which they were acquired and then continued to put out more F/OSS, things look bad (which I assume is your implication). I choose to instead make the comparison to the world where we never see this tech and it stays proprietary. Sure, eventually someone in F/OSS might have gotten around to building this solution, but they pulled forward the future and we get to see and build on the result for free.
