I think the fact that the charges indicate a massive pattern of corruption by FIFA and subordinate organization executives in a wide variety of decisions is quite relevant to the FIFA-bashing over the decisions regarding the way that the Qatar and Russia decisions, given the factual conditions surrounding hosting the cup in those countries, seem inexplicable on any basis other than corruption at FIFA.
Even if the charges don't include charges specific to corruption around those decisions.
It does not mean Qatar/Russia campaigns were corruption free. They do not have the evidence for it, or have not yet found a localization (US) vector that could aid in prosecution. My personal opinion is there was corruption (as normal) for both Russia and Qatar, but especially Qatar. The Jeremy Schapp ESPN documentary gives you a peek into things, including the bribing of local African football association officials.
Of course, don't let the facts get in the way of all the Qatar/Russia bashing.
