Most companies survive because they can make money. I don’t think Lightburn has made a dime on Linux systems. Even if they narrowed the scope.
Might want to read about why they are not doing this, many have had similar suggested in this thread…
Glad they did, but the realistic world of Linux is, pretty much, if it doesn’t make money it will be abandoned/discontinued. 
We are lucky to have developers that work for nothing to keep it alive… When was the last time you donated actual money to one of the Linux distros? Few of us do, but most do not.
I know it sucks, but that’s pretty much how the world works…
