What’s the point of discussing a license if you can’t run Blender on iPad?
You need to rewrite the whole GHOST part, since Blender uses macOS API, which is not available on iPad. You need to adapt the UI to iPad so that it would at least somehow work, not to mention how terrible it would be.
I can’t imagine that a desktop app works on a tablet as well. These are always two different programs with a completely different interface and workflow.
And besides, Blender barely works even on Mac and you want to add support for another system. No matter how wonderful it would be, it’s just not possible in the near future.
