We are being forced to dump slack for Teams. The only people who like Teams is Sales and Marketing for some reason. Not a single engineer likes this, and it will break every engineering convenience that exists on Slack.

As an ENG - I REALLY dislike teams - but I also dislike Slack

Slack should be emails that have been arranged into different folders - it just doesn't vibe with me for much otherwise (oo look you have 200 channels on unread - or, if you are the reverse, ooo look 200 channels with people chatting and I have to check every single one of them :(
