You are absolutely right. I’m not a moderator or anything like that.
This thread was about Sweethome3D and now it’s about bashing “bad” licenses again - but why not?
Sorry for me disturbing this discussion. I will adapt myself and sort out the bad behavior.
pspeed didn’t say something that I didn’t know before. I regard Unreal Engine as open source - and he doesn’t. You can view the source code of that engine. Their license is not BSD / MIT license but a much more strict and commercial license.
Just one little suggestion: You could create your own topic for questions around open source licenses. This way it would not derail this topic. It is only a suggestion - nothing more.
Also, in your VideoRecorderAppState question there were many good answers and infos for license stuff already. You started the thread 30 days ago: VideoRecorderAppState videos cannot be above 2gb?
Have fun,
