I have the same anti-Fox instinct, but I don't boycott their sports coverage or The Bear. I also try to avoid Amazon. But I'm basically a prisoner of Google (phone, TV hardware, YouTube TV) and not sure they're any better, especially in the AI era. We used to use Roku instead of Google TV as a better interface but the latter has been fine, better even, on this particular hardware.
I did find myself looking at ways to use third-party launchers that would cut down on ads/bloat and give you more control. Didn't get very far.
Anyway, as far as sports, this does kind of lock in Fox/Roku, NBC/Peacock and ABC/ESPN/Hulu, with CBS still lagging behind sports-wise. It's also CBS/Paramount/Warner you'd want to boycott politically these days.
