Ah, good old Ryanair. You can't beat their press releases - always good for a laugh. It's like listening to Alex Ferguson after United have lost a game.
Three of their six routes from BSL compete with easyJet - Porto, Alicante and London (if you count their STN route competing against easyJet's usually twice-daily LGW.) Bear in mind also that BSL is an easyJet base and they are not going to take intrusion into their territory without a fight. Porto is a case in point - a route set up from Ryanair's new Porto base to compete directly with easyJet. Maybe Ryanair just couldn't compete with easyJet and it had nothing to do with airport charges? Does anyone know what their load factors or yields were on their routes from BSL? Ryanair would never admit that, of course. It's always the fault of the airport, the airport operator, the regulator, whichever government happens to have offended O'Leary by not letting him fly to their country for free this week, etc etc...
All we need now is for EZS to adorn their BSL-based aircraft with "BYE BYE RYANAIR" logos!
