I'd be intrigued to know how Ryanair can influence another airline's HR department to such destructive effect? If it's just because they implemented conditions that others had probably only dared to dream about why should RYR be blamed if those others then try and follow suit? what makes you think that the airline industry should be insulated from changes that the vast majority of commerce and industry (apart it would seem from the banking sector) have been implementing for years?
As for the unpleasant aspects of flying with Ryanair, you're not forced to pay for anything you don't want on board, the food and drinks are as good if not better than that sold -or given away - on competing airlines (including BA's god-awful sandwiches), Ryanair aren't the first and won't be the last carrier to have questionable taste in internal decour and so what if there are adverts in the cabin - read the inflight magazine instead. The PA announcements I will, however, grant you can be an irritant...
