That's mostly because the Qataris are PR morons who can't help themselves doing terrible shit as a means to an end (though realistically, they couldn't have put on that WC without the horrible shit they did, which really just means that their winning bid was a tragedy that should not have happened). Doesn't mean that their sporting ambitions aren't directly related to their government's goals. Whether they succeed or not is immaterial.
Though while I do agree with the general point (Real have rather little to stand on if we're pointing at PSG, especially when bringing sponsors into account), bringing up Francoist Spain to deflect from Qatari PSG is a farcical proposition and is little more than cope.
