I totally understand your disappointment.
However try to look from my side. This is a 1 man project and it took a lot of time and hard work to get here. The main purpose of this release is to fund the future development. Ofc I could smile and release everything for free, but the long term consequence is that I get back to the office work and no more future versions are made ever. Sorry, that's how the life works.
As I already said, it was a hard decision. But it's necessary for now.
