This is so true and it's a danger for other ecosystems too. Once the big corporations throw their weight in (be it in a committee or only informally) they make their use cases dominant regardless how niche they might be for the rest of the world.

For example in Rust there is one big entity that currently pours a lot of energy into improving C++ interop. Now, this is not exactly a niche topic, but especially in a world where AI makes many rewrites possible that we wouldn't have daunted to think about a couple of years before, we shouldn't waste too much effort to save legacy companies enormous codebases at the detriment of our preferred language.

I think Rust has similar flaws as C++: too much unneeded complexity and abysmal compilation times.
