A lot of people find out that the W3C's governance is fucked up and overly dependent on corporate sponsorship (and it is) and then assume that the WHATWG must be a better institution (it isn't).
WHATWG is, for the most part, a "what-the-major-browser-vendors-say/do-rules" org. And keep in mind, that's now just two organizations (Google and Mozilla). That's good reason for pause.
