Because saying "Activision won't care as long as the product will sell" even though the game is COMPLETELY different adds value to the thread? People enter COD threads just to bash on it, so I will enter threads to call them out. Simple as that.
I said it myself : " People will have their viewpoints and they will be as constructive or unsupported as they want". That is literally in the comment you quoted. People are allowed to state any opinion they want. Going around policing and berating people is not the same thing as casually stating a personal take.
