As someone working for a company that is big on personalization (but working on totally different things): Yes! Thank you!
Even if personalization worked, I wouldn't want it. Not just for the obvious privacy reasons, but because it would not be relevant to my current context most of the time. If I'm looking at a camera review page, I don't want ads for flower bulbs or shirts or whatever else I may be interested in. If there has to be ads, make them relevant to the context. I would be much more likely to buy some camera accessories from such a page than something irrelevant and distracting.
