Refusing to let go of franchises, rushing their games to try to meet the demand, releasing new worse and worse copycat stuff every year only because it has the franchise's name on it (assassins creed, ghost recon, watch dogs, just dance, even far cry with the exact same gameplay since 3, the stories are good but they might aswell sell movies or shows and be just as successful and even less buggy)
Releasing videos about new games they're working on, thus hyping it up, just to not post any news about it after (Rainbow Six Quarantine, Beyond Good & Evil 2)
Taking Siege, their most successful game, and making it as unbalanced and uncreative as possible, with releasing 8(!) operators every year with the same abilities but tweaking the numbers a bit, and not giving two effs about the cheater problem thats infecting higher ranks (said by legit high-rank players).
Oh and the media is shining lights on the sexual harrassment in their canadian studio now, but hey, there's also a new and fun battle royale!
