Personally, I am perfectly happy with the google deal
I get a lot of stuff (maps, Android, chrome, chrome OS, docs, sheets, gmail, calendar, photo storage, music service, loads more besides), all free (in money terms!) I used to have to pay real money for this. What I give up in exchange is well worth it. I have nothing to hide, it's anonymous to 3rd parties, and if it means if/when I see an advert that it is relevant, rather than irrelevant, all the better....
Anyone that does care, either doesn't understand the deal, and thinks Google should give all that stuff for free, without any return, or they have something to hide, or they actually think Google is a person in a room, *here look, Andrew has ordered butt plugs from Amazon!!!! "
