I'm not convinced this is so problematic for me personally. The targeted ads are so good as to be creepy.
That said, I'm pretty sure most are bots and program driven, not an actual person doing the spying.
So, if I find what I want conveniently, while Google knows what product I want to buy, well... [Dunno]
The fact that bots are writing algorithms to watch me anonymously somehow bothers me less than being watched in person.
