This is what happened at that Mania.
Hart was scheduled to lose to Yoko. Hogan, finding this out, convinced Vince to let him win because Hogan believed sending fans upset home at Mania was not the right thing to do. So he went in there (at the blessing of Hart you see that he asked him if he could go in) and beat Yoko for the belt. He did show up on TV with the belt a few times but not many. The whole plan that on his way out he would put over someone and that one was Yoko - he did not think Hart could be the guy. Honestly, if you watch the HUGE pop he got for winning the belt at the end why do people argue with him? I'm not saying I liked it.
Hart/Hogan/Yoko all knew the deal of that Mania and agreed with it, I feel like it's in Bret's book and I feel like he didn't have anything negative to say about that event - I could be off but it's been a long time since I read it.
But this whole crap about Vince not trusting young stars or something, what are you talking about, Hogan was still on the roster so they had to use him until they couldn't. He is fukking Hulk Hogan. He started the "New Generation" after that so obviously he was ready for new young stars.
Obviously Hogan is legendary for shady backstage shyt, but I mean, if no one is even going to attempt to stop him then why would he stop? For example at that Mania, Yoko and Hart both could have threw a fit - they didn't.
As far as everything else, all the Andre shyt you typed was COMPLETELY off. Andre was nearing the end of his career and he put over Hogan. It was completely up to Andre if he wanted to beat Hogan, Hogan has talked about this multiple times. He has not been the best source on anything, but he has always been straight up on Andre - that's his hero.
As far as the Andre thing, I know about the backstage story- I'm not faulting the real life Hogan/Andre friendship. I'm talking about the on-screen Hogan/Andre friendship. That's all the original post is about- not a commentary on Hogan in real life, but the character on TV. The character on TV was heroic, but also did a lot of selfish things, especially to his allies. Just seems a lil' off in hindsight.
As far as the Hogan/Yoko/Bret situation, I don't doubt that the Mania IX was agreed upon before they went out there and did it... but Hogan did pretty much manipulate that shyt to his benefit. At that time, WWF was coming into a new era and I understood that they had to use him while they still had him, but it's been said (even by Bret) that Hogan's involvement in that whole thing came about through Hogan still having the influence to convince Vince. He then went on to barely even show up on TV with the belt, dropped it to Yoko because he didn't feel Bret was ready... if Vince was really ready to jump with the new stars, I don't see how stuff like that woulda even happened. It took Hogan dropping the belt and leaving for it to finally become about the new generation. Before that, it was very much about Hogan/Warrior/Savage/Flair, and once all of them were out of the equation (within a matter of months no less), the WWF FINALLY moved along.
