"At best dubious benefits" ??? I feel like there is a whole essay missing there, because my analysis of the situation is that it provides at minimum minor benefits to million of people using it on a daily basis, and at best it saves lives to some of them.
That it not to say there is 0 harm anywhere; we definitely need to do some cost/benefit analysis. But the initial premise is so obviously flawed that it's hard to consider the rest of the arguments.
