Some people are ok with mediocre, and that too is "fine", but you're right, Atlassian products are shite, they persist because of their ubiquity not because anyone I know or have ever worked with wants to use them.

Thankfully, they told industries like mine to go fuck ourselves when they discontinued the self-hosted options, and thanks in part, to COVID, there has been a lot of competition growing lately for developer tools like these.
