Ryanair has - surprise, surprise - objected to the plans to the airport's terminal 2 and has offered to build a cheaper terminal with higher pax capacity.
In fairness, one can understand FR's frustration, in that they'll face a higher pax service charge, but not benefit from the new facilities. That said, there is a measure of obstructionism for the sake of it, given that FR wants to make life as uncomfortable as possible for EI at DUB and delaying a terminal will obviously help in that.
It would be interesting to see the full extent of MO'L's proposals and the grounds of objections; I'm still amazed that no one has blown the whistle on the DAA's attempts to separate the cost of the terminal from that of Pier E.
