Long list, but here's a quick rundown - False advertising for d1. D2 PvP trailer was also seriously misleading, go look it up right now its -blam!-ing hilarious how misleading it was - Locking in game dlc that could be glitches into, the purchase just gave u the license to click the launch button in orbit - Bullying some of their own devs, ripping them off when Destiny was rebooted, then firing them illegally. Look up martin o Donell court case, similar thing happened to the writer/story writer/person who created the destiny universe and lore, but decided not to go to court and left instead - Locking off VANILLA content when dlc dropped. Most notably with curse of Osiris which also restricted platinum/achievements. They later changed it because they risked a lawsuit and/or Sony/Microsoft issuing out infinite refunds which they did for those that asked for them first. - Forcing ppl to repurchase content multiple times
