Earlier quoted context omitted.
We should simply start doing new standards through other organizations. There's no fundamental reason to float new standards through W3C rather than some other organization.
I'm completely confused why the W3C is relevant at all. This already did happen, the browsers created the WHATWG. Since the browser vendors' opinions are the only ones that matter, why do we care what W3C thinks?
You are of course right that browser developers/vendors get to decide what they're implementing. But web authors, OTOH, can decide which format their works are published in. Browser vendors and WHATWG have shown no interest in simplifying the web. Rather, they're piling up monstrosities of unnecessary complexity, with the effect that, willingly or not, it is becoming infeasible to develop a new browser from scratch.
Most of all, WHATWG seem uncapable to come up with any privacy protection mechanism; instead, we're getting DRM. Honi soit qui mal y pense
