The only way you will know they won't sell your data is if those terms are clearly stated in a contract between you and the vendor. Otherwise, you won't have any way to know they won't sell your data in the future.

Imagine if you are the owner of Everyday.me and Facebook comes calling, flashing a huge check. They want your data and are willing to pay big bucks for it. If there's nothing in customers' contracts stating you can't sell their data... cha-ching!

But if it's in the contract, then you know? That seems naive, you can't possibly know that they won't sell your data, but you can make an educated guess.

The point is, a user has recourse in that event. Without those contract terms, they don't.

I agree, but my point still stands. You don't know anything, but as you said, you get more "power"
