and Sourceforge now has a pretty bad reputation
The bad reputation is largely obsolete. The owner had changed to a bad owner with bad practices, but that owner was eventually replaced by a better owner again.
I still hate the UI though. We have much better alternatives today, which is why I don't see any reason for anyone to go back to (or start) using Sourceforge. It's no longer an issue of owner and bad practices, but solely of the platform itself with its UI/UX.
