I’d suggest that 95% of Jira complaints are actually about corporate culture which is felt most keenly through asshole PMs trying to micromanage you through a ticketing system. It’s mostly a fine piece of software - if you have a certified wizard to configure it it can be great… if you have a dummy it’s going to be barely usable - but you can say the same thing about github issue tracking.

The unfortunate thing is that the teams most likely to use Jira are also the teams I most likely never want to work on.
