I understand that most people want to move to other more modern tools, it's up to you. However, what baffled me is why the author's choice not to move is a problem? Did we pay them to move and they did not move as promised? Was there some crowd funding to move that was not fulfilled?

Might be it even not using all your code to train AI. Or at least not asking your explicit permission to do it.

And unfortunately some projects exclusively use sourceforge. Which breaks some of my CI pipelines.

yeah, it just works
