While all these things help , I still think it's true that for 99.9% of people, nothing really bad will happen because of info that Google collects. I mean, as terrible as "getting on the radar of someone that wants to make [your] life miserable" is, it's a relatively rare occurrence, and I doubt that Google is really making it that much worse (if at all).

Disadvantages as a consequence of being spied on by the "googles" of the world are difficult to prove , because of information asymmetry: * were you denied entry in a country because the agent had a bad day or because of something you wrote on twitter? * did your insurance rates increase because of a market adjustment, or because of something your car mechanic or car manufacturer shared with the insurer? * were you d…
Specifically to the things you list - again, I don't have statistics here, but based on my gut feeling - most of them barely affect anyone.

And btw, I kind of disagree with at least some of your items, like "were you passed for promotion because you're not good enough or because your employer found out through LinkedIn that you were looking for another job last year?". This is not what we were talking about, a case in which "Google" spies on you. This is your employer "spying" on you through your (supposedly public-enough) actions on social media. Changing the place you are looking for a job for from LinkedIn to "NewLinkedIn" won't make any difference for something like this, and is not the fault or responsibility of the company.
