Yeah I don't know what Atlassian's strategy was - presumably they were chasing growth and new customers, but I've never worked at a company that has paid for anything more than Jira and Confluence. I'm sure they have a whole list of other services but I've never personally known anyone to use them.
Actually one company I was at did use Stride and it was truly awful - I don't know how its product manager thought it could compete without such basic features as... the ability to edit and delete a message. But some fool at the company I was at chose it because it was cheaper than Slack.
I was using BitBucket for a while, to have paid access to private Mercurial repositories. Once they decided they no longer wanted to support Mercurial, and go with Git, I decided it was best to cut my losses and move to GitHub's paid plans. Atlassian has not handled offboarding of products very well.
