Earlier quoted context omitted.
This is the first time I've ever heard a person worry about the quality of the ads that are served to them.
I've often wondered why nobody brings this up more. If you're going to see ads for things, why on earth wouldn't you want them to try to better target you? The whole point is for you to find out about things that might be useful for you. Why would I want less of the useful things? Why would I want worse advertising?
Why do some people dislike advertising? Is it only that they are unmatched? Are there other reasons. If you wish to find an answer to your wondering, wonder on those issues.
