@jstenzel as I've seen it in the various threads there's no one actively working on the original repository who is able or willing to grant you access. Forks are a natural part of open source development. Since they have discontinued development on that package and you're continuing to develop it's pretty clear to users what they should use. The original FIROS package was only released into indigo. I'd suggest that you consider releasing your updated packages into newer ROS distros. You won't be duplicating any content as it's not there already. And as they've made it clear that they're not intending to continue maintaining you won't be stepping on their toes.
