Or bias, sure. But it cant be ruled out if they are willing to say 'weve been patient enough' or their complaints were made pre-game, and then this happened.
I actually agree with your latter statement there is incompetency surrounding this (as well as inconsistency)
The problem occurs when you have clear conflict of interests that need to be addressed and should be addressed, but arent, then situations like this happen.
The whole way that VAR is being implemented especially since Webb took charge screams 'they are sabotaging it to get rid of it'. Whether thats the case can be argued as conspiracy, and thats upto whoever wants to argue it.
A lot of decisions are now truly game changing. Before VAR, there was defo sympathy given how fast the game moves. Now, with numerous replays, minutes taken to review something in some situations vs a quick check in another situation can be very frustrating.
A lot of this stuff needs to be called out. Some teams have been quiet and probably tried to do it the 'right' way. I can see why teams are going the 'low' route now becauae this way it gets more media coverage, and more likely something will happen.
