I understand the anger against Ryanair aloofness and its dictatorship compliance, but I think it's diverting energy from the real culprits, which are the kidnappers and their boss.
Well, EU skies are no longer safe. If a journalist can be picked up, anyone can be. Ryann air is at fault, pilot really is - he could have kept his course. It would be a game of chicken and risky. So hard to say what is right wrong here. Most importantly, its the fact that EU is weak and Belarus did the math and concluded they would get away with it. Simple As that.
It's not like they called to the plane and said "we'd like to kidnap a passenger, please land" and the pilot went along with it.
