Ryanair demand subsidies from local governments to fly to far-flung airports. They can hold these governments hostage, as often the airports fail if they stop their service. Of course, this could be seen as simply "bad management" by our local governments.
And to finish, though this is something that applies to all airlines : no VAT or "eco" tax, that the rest of us have to pay.
In a sense, economics is entirely about what people like and dislike.
I’m sure positive externalities are a thing, but direct benefits to one party in a transaction aren’t externalities.
Of course, nobody is twisting the arm of these politicians. But the fact remains that Ryanair is exploiting this weakness to avoid paying themselves.
Type "Ryanair airport subsidies" in google and have a look at the first couple of titles. It's a mess that has been going on for 10 years now and is only now slowly being called a halt to.
