How many of their users do you think know they're being tracked like that? I mean actually know and understand, not "were notified in the fine print on page 27". Tracking users in ways they don't actually know about and understand, well, the usual terms normal people apply to that sort of behavior are "underhanded", "antisocial", "betraying trust", etc.
