This is a totally rational position to take, as a fan of any school, in my opinion. Of course his goals aren't aligned with UT's. He's not a UT alum or UT booster. He's trying to boost the profile of the school he played for and pours money into.
I've had numerous disagreements with the guy. He's not perfect and he'll be the first to tell you so. He's actually quite active in Tech online circles, readily engages with Tech fans and tries to be as transparent as possible, and I respect him for that.
That said, when he was a fledgling billionaire, he was trying to throw his weight around in the exact wrong way, and tried to push first Dana Holgersen, and then Art fucking Briles on the Tech AD. When he didn't get his way, he actually started trying to get Kirby Hocutt fired. He was apparently so obnoxious that his access to the department was effectively cut off, and it went beyond that, but I don't feel like getting into the rest right now. Luckily all that shit happened mostly out of the public eye. Suffice to say, he seemingly stopped being selfish, cleaned up his act, repaired his relationship with the AD, and is now a regent and has been making pretty good moves for Tech ever since.
Will it pay off? Who knows. The money and support is certainly there, and it seems to be getting there, but all that will matter are the results in the end. If they spend all this money and can't get in the CFP, oh boy.
