Bingo. It's about 95% "this has become really grotesque to watch" (also due to the NFL's fucked up morality in general, even in the context of pro sports) as opposed to, "Oh, I'm sick of the dumb Bears." Like, the Bears being hapless and doomed to forever suck is the cherry on top, but I really just lost the taste for football in general. Plus going to a football game has become one of the absolute worst things a human being could choose to waste their time on. It's everything that's horrible about sports fandom ramped up by a billion.
