I'll submit this for consideration: you're right, it's 100% fine from an individual standpoint. But there's an aggregate effect of some sort that is a concern. Every move like this changes people's standards and expectations. Call it a "cultural shift", and call us "conservatives" along this particular axis. If we don't want to live in a world where companies pull this sort of shit on _every_ user to the point that the privacy-conscious among us have no choice, we want fewer people around us to be okay with it.

So what does that imply we should do? I'm not sure. Maybe simply push back as we are. Maybe try to impress onto opters-in just what they're selling, and maybe they'll reconsider. Maybe ask Google to simply brand this differently. Call it the "Truman Show Package". So at least everyone is aware that, while the data being collected is valuable, and while everything is 100% a-ok so long as everyone consents, this is NOT NORMAL and nobody should accept it as such.
