Honestly, I think that SourceForge used to be easier to use than it is now. When it had its old interface circa (2002-2005 ish) I could find the information and do the tasks I wanted to do. It is difficult for me to find /anything/ on SourceForge these days, when I am forced to use it at all.
SourceForge was (and perhaps is) a great place for open source. I don't think it was a "lazy monopoly" or even a "monopoly" at all. There were always alternatives. Always other places one could go to host code and share code. When it was the most popular site, it was the best site. Now it is simply not the best site. I am super productive on Github, and unless something 5x better comes along I don't think I will move off of Github.
