Other than some issues I have had with EA's DLC system for certain games (cough Tiger woods cough) I really have not had any issues with EA other than they publish some great games that I really enjoy.
I've only once had to deal with their customer support over an online pass code that did not work but they handled that issue great for me.
Publishers are always going to try and make the most profit out of their games, every company tries to do this at some level. Yes EA has done somethings that clearly wreak of extracting more money from gamers. Its important gamers let give them feedback when they think EA has crossed the line.
