The project was cancelled in 2011, and according to the web page it's open source now, and I think that the open sourcing didn't happen until then.
Really? IIRC, in Jason Scott's excellent BBS documentary (you should go watch it. Like, right now. It's that good), Thom Henderson (from SEA. Remember them? I don't, because I wasn't alive. Which is why I have to rely on documentaries) said that it was expected in UNIX circles, which is where Kermit originated.
Or were you on PC? I don't know, I wasn't alive.
Kermit was not the only software you could get source code for. However, the entire ecosystem was much smaller than what exists today.
I'll concede it may have been different in more academic environments.
Of course, in the early days of unix, you got the OS in source form, but those were long gone by then. AFAIK, a lot of independently developed utilities were distributed in source form, in part because it was common to have to edit the sources and compile yourself if you weren't on the exact same architecture as the author. But that's just what I've heard.
Agreed. The BBS documentary is superb and really, really entertaining and engrossing. Especially the episode(s) on fidonet.
