No, the prospect of uninteresting ads is not my concern. AFAIK, Github does not build a dossier on me, using syntax hilighting to build a behavioural model of me and connect it with other people I may know. They don't integrate my syntax hilighting with my search term history. If they did, I would have the same concerns. This isn't about ad relevance, it's about my expectation that the things explicitly marked private (fence 1) in services that do not belong to Google (fence 2) stay out of the dossier Google has on me. Quite frankly, casting this as being about the relvance of ads means capitulating 100% to Google's proposition that if it makes me more likely to click an ad, it's worth giving them my privacy. To me, this is like arguing that if the police can make the streets safer, it's worth giving them the power to arrest and detain people without trial. It all comes down to the old, old argument about trading a little liberty for security. Privacy is a kind of liberty. If I won't trade it for security, I sure as hell won't trade it for figuring out that when I say "Ibis," I mean the bike and not the bird.
