Matt gets TONS of blowback every time he says anything less than complimentary about " Glee." We must not visit the same places online.
With that being said, there was only one time that he was quoted as saying anything really negative, and that was in a trashy tabloid. With everything else, he's made it clear that he wants to move on while still towing the "this show has touched a lot of people, and I'm proud to have been a part of it" line.
