It's still possible to talk about Battlefield 6 in the chat of the new Call of Duty.
Players have noticed that in the chat of the Black Ops 7 beta, mentioning the extraction shooter Arc Raiders is censored.
Content filtering in multiplayer lobbies is common for blocking profanity, toxic expressions, or insults, but censoring the name of a video game seems unusual. For comparison, mentioning Battlefield 6 in the chat is allowed. It is also important to note that the individual words "Arc" and "Raiders" pass without problems, but their combination immediately falls under the ban.
EA also doesn't allow talking about Arc Raiders in its application.
