I doubt that nearly every google workspace customer uses google's chat. Having workspace just means that google's chat is available. The enterprises I work with, when asked, have said that they use or are moving to teams, and chatting is either outright banned or restricted. Other than that, Slack is used for non-scheduled chats. I'm sure there are other programs that various enterprises use, but I've never met one that uses Google's chat.
