Nucore took the option to cancel the original agreement with all the parties, I am sure if they wanted to continue and pay the license fee per unit, the rights owners would be more than happy to continue.
They gave 30 days notice which they could have given the public.
The 3 originals developers no longer work together and with 5 or more seperate people putting their hands in the cookie Jar, I doubt it was done for a profit.
Ha but what do i know. I am sure they could have increased the price if they were not making money.
I am sure a replacement will be found, as the source code is available it can be run on a standard pc with some programming changes.
