Huh. As someone who has been in multiple Slack channels on various groups, I've never experienced the infighting. I think it one-hundred percent has to do with the culture that companies create and/or allow to foster. I don't believe it's a Slack problem, but a people problem. If the workplace you're in has a culture of respect and kindness, you don't have any of those issues in your communication tools. Interesting read, though.
