I think the STN flight being butchered is more to do with RYR's grievance with STN's charges. They ground a lot of flights from STN through the winter. Why LTN can't go daily, or why EI haven't jumped in with a daily Gatwick is beyond me.
Ah well. One of two things will happen. RYR or someone else (God know who) will get their act together and actually support the airport properly, with decent frequencies on decent routes......or it will shut.
