So you've traded one big company for a bunch of other big companies? I trust google with my data more than I trust Facebook or LinkedIn or Microsoft.
Google runs their own ad network (and it's generally an honest and upstanding ad network, unlike some others). All that data they collect on you is for their own internal consumption. If they ever sell their data, they are giving their competitive advantage to their competitors - not going to happen. Other companies are also logging and collecting every scrap of data that they can, but they aren't consumers of that data. It just gets sold to the highest bidder. I'd much rather have google tracking me and know where that data is going, than have somebody else tracking me and never knowing where that data is going to end up.
