I love it, although ethically I think this kind of thing is only reasonable if they hide the feature or make it hard to disable. Having it opt-out makes it borderline in my opinion but I can't argue with someone who thinks opt-out is enough to put it over the line. For example, I like the various different google fuzzers that generate fake searches to hide your real ones in the noise.
