For historical context, I’ll add this:
I felt quite certain that at some point after this there was a thread/post somewhere on the forum mentioning how BDK / Numata had originally planned to freely share the Madhyama, but then changed their mind, however, I can’t find it anywhere so perhaps I dreamt it! 
Anyway, I think the concluding comment of the linked thread (from three years ago) about sums things up.
