I can see your point, and agree that it's daft to suggest we're all apologists for the UAE, but it's surely easier to make the link where the people clearly support just one team, and that team is owned by an entity linked to a state. Sports where the occasional event is held in a state, or where people are "fans" of individuals etc. are very different.
In other sports it's often the players who are the ones getting grief. The LIV golfers certainly got a shitstorm raining down on them (albeit things have got more complex since), and the players who went to Saudi faced plenty of criticism. Bein and Qatar have also been linked to sportswashing repeatedly in the media, but there isn't really a Bein fanbase to attack.
The other key difference in being fans of a team, rather than individuals, a sport, or a TV station, is of course that you have more obvious rivals. Rivalry between supporters is almost entirely based on hypocrisy. Their players are shit, our are great. They get all the decisions, we get hard done to. Their owners are worse than ours.
