Advertising works because people have little choice in the matter. It's exploiting that people value "consumption with ads" more than "no consumption at all", and most are not skilled enough to remove the ads themselves.

(It's not like they wouldn't do it if they knew how; remember the popularity of VCRs? Their main use case was that on a recorded show, you could fast-forward through ads.)

People are not OK with metrics; most population has no understanding about the extent to which they're being surveilled or measured. There's also a growing feeling of helplessness, because the more the snooping is becoming known, the more apparent it seems that it's the same as with advertising - unless you're a tech-savvy person, you have no choice at all.

EDIT:

A big part of the problems are the constant lies of omission. I believe much fewer people would be willing to connect their TVs to the Internet if on the box, next to "you can watch Netflix from your couch", there would be text saying "we'll spy on you as much as we can, and this data might wind up at your insurance provider". Or an asterisk next to "Netflix" explaining that "the service will work until we get bored or they change their API, i.e. for about two to three years".
