> It is already the case that Google and Apple can push (more) surveillance into your device anytime. GACT does not change that. It does legitimize it and that is a very important thing. Right now, pushing this kind of thing covertly would be disastrous if (when) it is discovered. With GACT, it's already there so it's presence alone is not suspicious and can be enabled surreptitiously. > Or should we abjure smartphone-powered contact tracing? Yes, in its present state, I think we should. We've done without smartphone-powered contact tracing before so it is clearly not essential. In its current form, it is worse than the alternative of traditional contact tracing.
