This post is quite misinformed, IMO. Yes, many apps ask for the permission to post to your wall. You can say no. You can also go into your Facebook settings and remove that specific permission from the app, and then the app can no longer post as you, but the login functionality would still work (assuming they were halfway competent in their coding.) I often will remove the wall posting permission right after I grant the permission. And as to the proposed solution, Facebook doesn't need to do anything. Those developing the apps don't NEED to ask for the permission to post to your wall. The developers (and business rules) determine what permissions to request, and we frequently build apps where all we ask for is basic information or basic + pictures, for example. There is absolutely no reason that the developers MUST ask for permission to post to your wall except that they are going to do it, probably without asking you first (which is EXACTLY what you granted them permission to do!) So the answer to the problem is, don't login with apps that require you to grant permission to post as you. Or, immediately deactivate that access if you must use that app. Or do as others have mentioned, and just set that app to only be visible to you. You get the "benefit" of the posts, and it doesn't go out to anyone else. The real problem is, most people just don't care. Facebook gets 80% CTR on permission dialogs, and almost 50% of people prefer social login to creating an account or using a guest account. Facebook has a great incentive to make sharing as frictionless as possible, so we are only going to see more ways to share things easier. I'm not saying that sharing is bad or evil, just that people should be making that choice consciously, not just blindly clicking it.
