Probably more to do with the fact that they agreed to serve in the grounds and a few days before the tournament is due to start reneged on that promise where FIFA don't have much choice but to except.
But on the other hand I can see why Qatar might be a bit pissed as that they're being criticised left, right and center on all manner of things even after relaxing their drinking rules to try and appease us, so they're probably like sod it.
