It sounds like this is trying to coin a new term. I hadn't heard the word forge used to mean an all-in-one git+issue tracker+project mgmt+etc. suite before.
Yeah, it is funny to read all the assertions that everyone knows what a "forge" refers to in the middle of all the threads wondering wtf a "forge" is...
Once upon a time, a lot of software was released/available through "source forge", which is pretty self-explanatory in the context of software publishing. Then a decade ago, SourceForge shit the bed and destroyed its reputation. I'd bet that most of the developers saying they've never heard of "forge" in this context have entered in the industry in that time.
This is a bad association even for people that recognize it. Presumably there were good years but most will probably remember the ugly endgame with awkward UX and weird ads masquerading as fake download links.
Yup! That clears it up. It’s the site that serves lots of ads and binary packages of some old software. At least as of the last time I looked some years ago.
Ok then, not sure I would want more things like that today to self host, but to each their own.
