As we've been reporting for a while, there was a back and forth over whether Batista would be staying through Extreme Rules or through Payback. Some reports suggested that the Animal was finishing up because the company wanted to book him as losing to Daniel Bryan, but the problem isn't Daniel Bryan but rather the company breaking promises to Batista as we've been reporting here on the website. It's not a personal issue between Batista and Bryan where Batista refuses to work with him. "WWE wants that story out, but it's all twisted," the source said. "(Batista) would do five jobs for Bryan. They've f---ed him in money, booking, broken promises (relating to his) schedule, and promoting his (outside projects). Had that not happened, he would be around until late June, but because Vince (McMahon) f---ed him, he's not."
The source adds that the company is quietly trying to promote the story of Batista not wanting to put over Bryan in order to turn opinion against Batista, noting, "...they dragged Daniel Bryan into this to vilify Batista. Daniel is beloved and a martyr so he benefits, but it has nothing to do with jobbing. They've twisted. It's classic Vince. Look at Ultimate Warrior and SummerSlam, Bret Hart in Montreal. (Vince) puts out his narrative. There are always two sides."
The source adds that Vince McMahon is directly involved in trying to resolve the situation and that things are tenuous right now. As for Batista vs. Bryan, the company didn't move ahead with that because they want a multi-pay-per-view program with the two and that's not possible with Batista's promotional commitments to Guardians of the Galaxy.
Obviously this is all from one source who may or may not have a grudge of his own, so take it with a few handfuls of salt.
