The discussions about Google (et al) tracking show a strikingly similar pattern to discussions about clandestine government surveillance: a fairly even split between people saying "that's not what they're doing" (they only listen to explicitly triggered searches), "it's appalling that they're doing this" (it's a privacy breach) and "we've known they're doing this for years" (how else would they have such good speech recognition).
