As others have already mentioned, it's a trade off. They remember it for you, wholesale. This works out great when you need to install an app that you bought already onto a new device, etc. The people who really care/need about this type of privacy are surely not "scared". They already know how to avoid these helpful service, right? It's not rocket science. If it matters to you, then you figure out how to do it. The paid app vendors (Apple, etc) really are trying to be helpful here, not nefarious, imo.
