I'm sure it gets to him to see officials unfairly criticized. You could kind of tell in how active he was on X around this particular call. This confirms it:

“I get it. It goes with the territory,” said McAulay, who now works as NBC’s rules analyst for NFL and college games and is not shy about criticizing the work of officials. “But when you use the word ‘stolen,’ that’s a different mindset. That’s coming at it from a different world where you’re challenging their credibility, their integrity, and that’s where I always draw the line.”
