Then comes the question: would it also obviously expand their domain of allowable actions to trespass on their users?

Since that is a resounding "yes" and they also have the extremely obvious finance incentive to do so...

Legal is there to advise you. Sometimes what legal tells you is not in the best interests of your company. A good legal team will work with you to identify when maximal risk-averseness is not the right strategy.

A normal legal team (as opposed to a good one) will always recommend whatever is virtually guaranteed not to come back to bite them.

Yes, so you claim you can do whatever you want with everything you can get your hands on and then social media blows up because it's batshit insane, but don't worry because you're _legally in the clear_.

You're acting like they didn't have the 2nd option of just not selling the data so the current wording is accurate...

On the other hand, if legal recommends that they reword their TOS, their users also should probably listen to them.
