Normally I would say "That's what standards bodies and governemnts are for", but in this particular context both have failed. It's been thirty freaking years since the ADA, and most websites are still not accessible. Standards bodies both move slowly and are historically bad at achieving widespread implementation in reasonable timeframes. The other answer is "Browser makers"... but that's also Google. And maybe Mozilla, which is arguably the "independent, non-corporate entity" you'd like. Really though, this works because Google has the technical chops to make it work and the positioning to make people want to do it. I cannot think of a single "independent, non-corporate entity" that's both positioned to do this and capable of it.
