What people (myself included) seem to really object to most are privacy invading personalized ads. These don't just provide benign info, they are actively taking something that belongs to you --- your privacy.
The more benign alternative is context sensitive ads --- ads based on the topic at hand. If I search for "pet supplies", I can tolerate and maybe even appreciate a few ads for dog food and flea collars. This might be distracting for cat owners but this is something I think most would be willing to accept in exchange for the "free" service.
DuckDuckGo seems to be growing very nicely with context sensitive ads.
