I agree he's not selling it properly, but I would also say it's not actually that different to everything coming back to my email inbox and being remembered by my browser either. For me it's not a problem, perhaps for admins it is, which reminds me of the incessant caterwauling we used to have about "the spam problem" (which was often a mask for the micropayments movement). And people should reach for their gun when they hear people blabbering about ID centralisation, that's a good reaction. And considering there is a happy-go-lucky Belgian linking it to the government in the comments, I'd say they are right in some sense, it will embolden those who want the government to control everything on the Internet.
