If you are just using WePay for buying food, as a customer you don't pay anything extra. For store owners, let's say a small shop that sells breakfast buns, the money to pay through WePay is usually sent directly to the owner's WePay wallet.

IMO, the world needs to pay more attention to this, as we implement more and more AI applications. What worries me more is that we still don't really have a good solution to his problem. Pretty much every model that is defended can be attacked in another way.
My guess for now is that we would have to go all the way back, and question about the assumptions we are making about high dimensional spaces, and use a more rigorous way to prove theorems and lemma about AI systems, rather than experimentally saying the accuracy is high enough therefore it works.
