the generic, nontechnical FUD response to the apple/google contact tracing initiative is really sad. i read the docs the day they came out. they're not scary, and i'm an extreme privacy advocate. even moxie got in on the act, which was lame as hell. it's just posturing.
i've not seen one person (including moxie, who made plainly incorrect technical claims) who read and understood these technical documents then leveled legitimate criticism at them.
