the criminal charges and sackings were in-part a fallout of the 2011 Fifa presidential election between blatter and some qatari guy. That let the cat out of the bag, the agencies started buzzing and Blatter set up that Ethics committee. Remember, earlier, Germany got away with corruption, so did South Africa.No problems? The whole process saw people face criminal charges and a swathe of FIFA sackings.
Infantino did a smooth-over job after the shit storm, but as far as the bidding process goes; as I already said, they couldn't pull that stunt twice in such quick succession.
Also, "officially", Russia and Qatar were absolved as well. So, neither states(and other states as well) care if a bunch of Fifa execs messed up. The rest of the fifa elite will simply shrug them off as fools and make mental notes to not spoil the broth.
The whole point of a Fifa WC, to me, seems to be projection of a nation's soft power. I don't expect the execs of fifa and various federations to give up that power of swaying decisions in your favour in exchange for a few million dollars
