I heard/read somewhere from some Stewardesses on those budget airlines that even though people get angry about being charged those additional costs, that they claim they will never fly again, that they actually continue flying repeatedly with the same budget airline. I think the term used was "hate flying", that you hate the extra charges you get but continue to fly because it is the cheapest.
You can avoid all those charges by simply playing their game.
Minimal luggage, no extra crap like speedy boarding or so, be prepared to forfait the money if you change plans (change of flight is usually horrendously expensive) and alway print / mobile app your boarding pass.
