A cynic might surmise that the Paris press conference was perhaps called by Ryanair in the hope that a commercial negotiation with Aéroports de Paris would turn out favourably in time to make a big announcement (and as a way to put some pressure on AdP to make concessions), but then AdP unexpectedly didn't play ball, and rather than lose face by cancelling the press conference entirely, Ryanair reheated some well-past-its-sell-by-date BVA route news as a flimsy pretext.
Complete conjecture on my part, of course, but why else hold a press conference with no news?
Unlikely as ORY or CDG don't need FR but FR need them and those airports would have no real reason to offer FR discounts or even enter talks. Take it or leave it.
