The biggest factor in Hogan leaving is obviously some sort of scandal. You don't take someone off of the WWE Hall Of Fame page unless some very serious incident has gone down. The rumour is a racist tirade that was recorded on tape. Supposedly this will be released at some point soon and WWE wanted to stay ahead of it. The news reports won't read "WWE superstar" they'll instead read "former WWE superstar", and that makes a big difference. However, remember that this is still just a rumour. It could be something else, but clearly there is a huge main factor in play here. Surely it has to be something that is very controversial, otherwise why would they kick him out of the Hall Of Fame? Whatever has gone on, all the factors summed up in this feature represent the fact that Hulk was expendable. When the going got tough, it was an easy decision to make for WWE to rid themselves of him.
