Am I right thinking this suite used to be free until the licenceholder changed?
Absolutely agree! (popcorn) Got this free from purchasing a pro body few years back, and well at first, thought it was amazing since I didn't really play around with RAW files beforehand, then discovered other software, such as RawTherapee, which is both free and much more advanced for the possibilities with your RAW image. I found this to be EXTREMELY limited (annoyed) I now have invested into the Adobe creative cloud and will never look back (y)
As a Nikon SLR user for over 10 years, with multiple bodies, I would stay away from this. It was once good, but has not moved with the times. It does have some USPs, like being able to import the picture settings correctly from NEF (RAW) file and using control points, but otherwise Lightroom and other tools are far better, even at those at this price point.
