Mostly because of the horrible f2p restrictions like "pay for quickbar", "pay for quest reward", "pay to show title/legacy name" or "pay to hide helmet". If BW monetized the jedi classes instead of these restrictions people would not be talking trash like that. on top of these, a person who pre-ordered the game and/or bought after release played a couple of month then stopped; they found out that they get same treatment as the person who spent 5$ in cash shop. this was a huge negative point. by february 2012 swtor had 1.7million subscribers, let's say we now have 500K subscribers, there are 1.2million who did not re-sub. if treatment were better at least half of them would still be active subscriber.
