Racedo
Most of what you've stated has been covered by pages of comments, especially the BA disputes along with fuel surcharges etc etc. In the Virgin incident I'm sure the crew would have wanted the passengers off the aircraft as soon as possible. (The US Authorities are very strict about this) They couldn't because there was no customs and immigration available. The only thing Virgin were guilty of was diverting to an airport without proper facilities. But the article doesn't mention why they diverted to Bradley.
Facelookbovvered is absolutely right by saying Ryanair has dragged the level of customer service into the toilet. They have proved many times that they don't care once you have bought a ticket. They have introduced charges for everything thereby bringing their service levels to nothing. What do Ryanair offer these days that you don't pay for?
Remember customer service levels are usually set by Companies. It's the individuals who can make or break it.
