I don't know the specifics of the situation. I generally assume I'm only getting part of the story when I read these sorts of articles. However, knowing Dr. Lukacs, he is most probably correct and in the right on (almost?) everything he is saying, and he is most certainly being royally f*'d over by the university.
That being said, it was just a matter of time until he went up against someone who didn't appreciate his lack of social skills. He is certainly not a diplomatic person by any means. He's one of those guys who would go up to you, tell you how everything about you is wrong (assuming you are in fact wrong), and be honestly perplexed when you get upset about it.
In short, he reminds me of that scene in The Big Lebowski: "You're not wrong, Walter, YOU'RE JUST AN ASSHOLE". This guy is Walter. He's not wrong, but his lack of tact pissed off someone in power over him.
I hope he comes out of this on top, because (as far as I can tell) he didn't do anything wrong, and even if his conduct was in error, seriously university, thanks for giving my degree a bad reputation (by proxy; I got CS, not math).
Just some insight from someone who knows the guy (me!). Hope you find it interesting
