FT2 Author's (GenAI generated) Statement
@dl9et I have the feeling that his post confuses "proprietary" with "closed source" ... JT4, JT9, JT65, FT8 etc. all are described openly on how they're coded and decoded ...
@DO2SGF Yes, that is one of the confusions.
There are a few more though, the (AI generated) statement is all over the place.

@dl9et I mean... forking a #gplv3 licensed software, giving it another name and publishing the sources alongside the compilated code is fully legal, but forking it, publishing compilates and ignoring the GPL with statements like "it's my work, I have all rights on my code so I can keep it closed" or something in that style... no, buddy, that's not how the GPL works.
(Relying strongly on an #ai being trained on, probably, masses of GPL-licensed code lets this sound even more... interesting.)

TBH I lost track on what the state of it all is now...
