I can't agree more strongly. I sat down to write a letter to the FTC, and I can't even articulate my objections because after reading this spec my only response is encompassed in "WTF is this shit?". I've worked in my past with members of the Chromium team and I've generally found them competent and well-meaning, and I can't see any amount of well-meaning (and some lack of competence) in this spec proposal. This feels like a shift in the behavior for Google far beyond their existing slow drive to consume everything, to something far more draconian and direct.
