This is so stupid. Isn’t this a free-to-play game? With one-time-purchase games you can try to fool people, then take your money and leave while people complain about the game behind you.
But this is a free-to-play game, they intend to make money by gradual ongoing revenue from in-game purchases, etc. You can’t fool people who are actively playing the game.
The contract hurts their image, and prevents them from receiving critical feedback.
