I think that when the inquires into the recent reported Ryanair fuel shortages in Spain you will find that the air traffic services were less than proactive, this has been conveniently ignored by those who are trying to make a political capital in faviour of the old protectionist ways.
I am not saying the Ryanair management are whiter than white just that there are others who are quite happy to be very economical with the truth to further their anti Ryanair objectives.
