This is just a hypothetical question which popped up in my mind when I was using an yahoo email to authenticate a service and suddenly remembered yahoo is getting sold. what happens if the buyer decides to shut it down.
See why proprietary oAuth is actually not the best idea ether?<p>I remember years ago i hosted my own auth server, and many websites actually let you put in your own "auth uri". Was that oauth as well? What happened with this?
