That's valid, but saying that a product a few developers created for FREE, and made open source so anyone could copy and change is the "wrong thing to copy" is just disrespectful.
It would be disrespectful if thats all they said, but including "it would be nice.." and "...imho" changes it to politely giving their opinion on a third party forum. If it were a show hn, or the projects own forum I might agree with you, but this is the appropriate place to give armchair opinions.
One of the problems of Jira is that it allows you to make any workflow for its issues.
Bugzilla had a "this is how it's done, and that it is" attitude to bug tracking workflow - it wasn't configureable. As such, it couldn't be perverted into a dozen gates with different approvals needed for each gated step.
It's really easy to copy Bugzilla's structure into Jira. It is very difficult to keep management from changing it into something else in Jira.
Or maybe just to reach someone who never used bugzilla and doesn't realize it's light-years better than jira or rally.
