FT2 Author's (GenAI generated) Statement
[Wsjt-x-improved-community] FT2 successfully reverse engineered as open source! | WSJT-X Improved

@dl9et Link geht nicht ?!? EDIT: geht aus dem WLAN. Nur Telekom handynetz blockt
@dl9et Danke! Ich habe mich da ganz schön drüber geärgert und auch die Sources verlangt. Gab aber natürlich keine Antwort. Finde gut dass sich da die Ham Community rein hängt.
@dl9et aber ~160 Hz man bekommt doch in FT8 schon auf dem 3kHz Fenster schon kein Bit mehr ungestört in die Luft. Das wird schwierig. Dann hört es noch ~8dB schlechter. Da machen die 100W FT8 Leute demnächst Legal Limit, um das auszugleichen. 😆
@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...
