It is the fault of these "fans". You pour money into a club and league you have no actual affiliation with, leading to the disturbing centralisation of the sport which has led to the shitshow we have today.
If people poured money into their local clubs and leagues instead of going out of their way to pay for foreign leagues, the sport at global club level as a whole would be infinitely better off, and we would not have to deal with the bullshit we do today.
I mean, UEFA are to blame to a great extent too, but everyone knows that already and are happy to blame them. International "fans" aren't so keen about blaming themselves though the way they should.
The truth is though that the damage has already been done - any Super League is merely a mild divurgence from a path we are already on.
