You've identified the problem, but I think you're wrong about the cause. It's not internet centralization that's the problem, it's the mundane fact that JavaScript does not have a large standard library. And JavaScript absolutely should have a large standard library, but it's not clear what organization would have the motivation to implement, support, and promote one. It's not impossible that a community-driven effort could accomplish the same thing, but nobody seems to be working on it.
