It's more like Jira than GitHub. Jira is still widely used, even though FogBugz is much better quality.

I use both because of different companies we work with. FogBugz is much friendlier, but Jira does more. And Jira also has a massive number of free and commercial integrations available. When DevFactory purchased FogBugz from Fog Creek they went into rent collecting mode. They keep the lights on, but they are not going to renovate or introduce new features.

It works for us its fine. After this stunt however I'll be pushing to migrate to jira like the rest of the company
