Are Matt Stone and Trey Parker Behind Cruise's Ouster?

It sure makes a lot of sense but is just pure speculation and innuendo.

Viacom Conspiracy Theory: Please note that the pissing contest between
Sumner and Xenu began on the same day that Paramount announced a two picture deal for the South Park guys. How's this for a scenario: Tom gets wind of the deal and calls Brad Grey telling him to cancel the Important Pictures pact or
he'll leave. Brad Grey kicks it up to Freston who kicks it up to Sumner who
-- knowing that negotiations are going poorly and not so fondly recalling
being forced to pull the Trapped in the Closet episode or else Cruise
wouldn't do press for MI3 -- says, "Fine, goodbye. You and your alien race
will bully me no more."

Redstone seems like the kind of man that doesn't like to be pushed around by his employees so instead of just quietly severing the ties he fires the guns on the way out. I mean Redstone could have just said they didn't want to renew Cruises deal but instead he blasted Cruises weird behavior in a press release. He is making it known that Cruise is the one that forced himself out by acting like a space cadet.
