Lots of people with better reputations than Bright have publicly lobbied against disclosure of any sort. Bruce Schneier is a great example of this; if you're an old industry head, Marcus Ranum is another name here. The point isn't that everybody agrees with me about "Responsible Disclosure"; it's that everybody who matters does.
And project zero puts an emphasis on disclosure, not coordination. When the ticker runs out they nearly always disclose, regardless of where coordination is at. That's what Peter Bright was ultimately complaining about; they disclosed like a week before one of the relevant patch tuesdays.
Like I've said, the primary point isn't the coordination. That's the carrot to get the vendors to play game on a sane schedule because otherwise the vendor holds all the cards.
