I and the whole rest of our LabVIEW community are the ones with the vested interest in OpenG. To me, the new github location looks less like a fork and more like reviving the project. LabVIEW isn't my day job anymore, but it is still my nights-and-hobbies job, and I welcome any action that brings things back to life.
For instance, I took a look at JKI's OpenG-NXG github project, and there hasn't been a commit to any branch in over a year, and not to master in 3 years.
