Context: Certain Call of Duty content creators are exposing Activision over greedy practices and ruining the entire playerbase. According to previous videos criticizing Activision's actions, the continued unfair treatment of Call of Duty community by Activision has triggered furious response by some of Call of Duty players.
My recommendation: Even you're buying for campaign, DON'T BUY ANY CALL OF DUTY PRODUCT.
Haven’t even pirated a CoD since MW1.
