> why should google care?

Well, if "we" want to prevent a scenario where Alice provides wrong/loose identification to Bob and Bob accepts it, there is only really two realistic ways to do so: force Alice to not do this, or force Bob to check (maybe with "our" aid). Or do you propose having Victor who would regularly come by Bob and check all of the new identifications provided from the all of Alices in the meantime?

I think yellowsir actually has a point, and I'm the one they responded to. For search I think Google should care, as their users will eventually leave if they can't find reliable information. YouTube on the other hand... I don't see any business reason for them to care about content quality or authenticity - they make money from every video people watch.

To my first point, I don't know how any Google competitor is going to provide more reliable information until the root problem of authenticating sources is solved. So maybe there is really no reason for them to care after all.
