what about existing forums with large userbases - will i have to contact every member to get their approval?
or even the facebook api - if i use the facebook sdk, does that count against me or is it facebook who need the permission?
or even simple things such as remembering someone's shipping preferences in a cookie to speed up checkout for other products. does that mean i'll have to ask for permission for that too?
it doesn't seem very clear to me and imo it goes against our unobtrusive efforts to make our site easier to use.
