The suggestion that the EU are engaging like this gives a hint it is not an outright no, but 'subject to' and that is very concerning....
IF it was a clear outright No then I believe the decision would already have happened and been communicated............its neither at the moment.
Problem the EU will be faced with is that a No will be challenged in the courts.
Ryanair I believe will state that they have again and again met conditions asked of them and that will give EU a problem.
If EU says No, even after everything Ryanair have offered, then a clear danger that a court will find that the EU has never been acting in good faith. This could get really expensive if a court found against EU because then would expect a lot of damages.
