Infinity Ward has retired one of the emotes available in Warzone and the multiplayer of modern warzone for reasons they have not specified, however, taking into account certain far-right usages, it is possible that the reason behind this disappearance makes more sense than it seems.
Gestures that, unfortunately, exist

If you play Call of Duty, either in its multiplayer variant or in the battle royale Warzone, you will know that there are a series of gestures with which you can quickly express yourself with the rest of your classmates. Activating them, the character performs an animation in which he shows a series of hand gestures such as thumbs up or OK, so that we can communicate with another player without saying a word.
Well, one of the most basic and recognizable gestures, the OK one, has disappeared without warning, and the suspicions that revolve around its withdrawal have to do with a certain racist use. As they point out in eurogamer, the Anti-Defamation League added the OK sign to its list of hate symbols after it became known that it was being used to express white supremacy. The gesture used in this sense tries to use the three fingers to create a W and the circle of the thumb and forefinger to create a P next to the palm of the hand, giving rise to the initials WP (White Power).
The current meaning of OK

The origin of this reasoning could be in 4chan, where supposedly a tendency to believe that the OK symbol hid a meaning that ended up twisting to be used by the extreme right was born. Knowing that, and now that the racial issue is in a critical situation in the United States, the presence of this symbol in Call of Duty only put Infinity Ward's commitment to maintaining the cordiality and civility of its community at stake. , so with the idea of continuing to respect the message of Black Lives Matter, they have probably been quick to eliminate this potential source of hate.
The new 'Okay' emote has been the best one added so far from modern warfare
The company has not made any type of confirmation in this regard, so at the moment we cannot confirm that the reason for the withdrawal of OK is due to this, however, knowing that even Blizzard did the same in 2019 after receiving several complaints from users, something so simple and simple may have become a quick speaker for the most cowardly, so there is no other option than to eliminate it.
