These founders need to be very, very careful. Business-to-business services that are disliked by the public and involve any type of tracking or analytics aren't just class-action-lawsuit bait, they're ambitious-prosecutor bait.

Judging from reactions here, they're not going to get much community support when the legal backlash inevitably happens, either.
