People working on open source "hackery" stuff are probably much more likely to be familiar with Github / Gitlab issues, or Bugzilla. I can only think of one open source project that uses Jira; it's my only encounter with the program, and it's without question the single worst experience I've ever had reporting a bug to a project from a technical point of view. I'm not so sure about the subversion comparison. Maybe it's out of date - someone who got started programming in the last ~10 years has probably only ever used Git, whereas plenty of organizations use Jira, as far as I know.
