Everyone complains about Ryanair, but they still buy the tickets.
Because of their terrible customer service, denial of flight on multiple occasions to people I know for trivial reasons, and rip-off terms, I don't travel with them any more, and wouldn't encourage anyone else to either. So no, not everyone still buys the tickets. They are the worst airline I've encountered and I suspect this won't be a good strategy long-term.
More than the terrible customer service, I really dislike the idea of local administration (i.e. unwilling taxpayers) to give them subsidies to operate in certain areas. This is a disturbing way of preventing other competitors to expand in the same way.
