Be careful what you wish for....
To learn more about protecting privacy I have been playing around with VPN's, virtual one time use VM's and strict browser settings to reduce exposure to the evil G.
The result is that I now get bombarded with cat food, lipstick, perfume and mascara commercials when watching my daily sequence of history, car and gun youtube videos.
It really amazed me that this happened, since none of the commercials served make any sense based on the selected content.
Probably it is just G's way to flip the finger.
My take from this is that it is debatable whether creepy ads are worse than non-sense ads.
If cookies are the price to get relevant ads, ads which will be served anyway since sites like youtube cost fortunes to run, perhaps it is an acceptable tradeoff.
