I don't think that people have double standards for Google, it's that the potential flaws aren't obvious.... Where's the competition and alternatives? We're stuck between making decisions too quickly and Google becoming the de facto standard.
EDIT: To be clear, I find Google's actions in this regard to be surprisingly impolitic and ill-conceived. Anyone who reads it should have alarm bells.
Google should respect the desire of other parties to be given adequate time to review their proposals. Being told "you have to object NOW because we're going to ship" doesn't allow third parties to actually identify technical issues. It's like someone committing code without letting their peers review that code for flaws. It's a recipe for cementing flaws into the web platform. Intended or not, there is arrogance in the notion that external discussion of Google's proposal won't improve it.
