It's not a Ryanair thing, in fact whenever I fly with Monarch I get ready to be slammed against my seatbelt more than when I fly with Ryanair to the same airport.
If it was that much of a concern, I can assure you Ryanair would be straight onto their crews about it. Considering Ryanair is the very airline that would take pens from hotels where they would have conferences so they didn't have to buy pens for their office staff.
