Contextual advertising (what you’re describing above) is a lot less intrusive than hyper targeted advertising.

The former evaluates the context of the content being delivered by the server, while the latter evaluates an encyclopedia’s worth of data (both inferences and known traits) about the user.

I agree. Contextual advertising is less intrusive. What I also believe is that it is also very relevant and there is a debate about whether hyper targeted advertising actually drives more sales.
