I would call a lot of the DLC strategies used today, unethical. Charging extra for something that should have been included in the main product, or even actually including it and then charging for unlocking it is just plain wrong. I would even go as far as to say that this type of bussiness practise should be criminalized, because we cant allow companies to do whatever the hell they want in search of profit. Thats not democracy, thats idiocy.
