I'm on my phone and won't write here my point of view on the topic, but I will point out that the dlc was not billed merely as a gift, but as compensation for reduction in price of the base game, to those who have already purchased it at the original price, and as such people are free to judge this compensation and voice their opinion.
Whether we were owed any compensation at all in the first place is another matter, games see their price reduce at some point after release all the time, however it was promised.
