You have more of a voice in the W3C than any other standards body (you can comment on the github issues, or join as an invited expert etc). The W3C was created by Tim Berners-Lee, if anyone should have a vote on how web standards are run, then the creator of the web should be one of the contenders for it.
>And the W3C had stalled progress so much in the 00s and 10s
Not the 10s, just the early part of 00s, due to the xhtml vs html5 thing.
