As a LightBurn user and license holder, this is annoying, but I could see this being a good thing in the long run. Right now, there is very little opensource alternative to LightBurn. As of today, there is a much stronger incentive to make it happen. I’m hopeful this spurs on a modern tool in the open source community that works as an alternative. What LightBurn might have done is save them selves some support overhead and created competition. We’ll see how that works out for them.
