Sourceforge had his time. As MySpace had his time, too. They where cool a few years ago and where the best thing that could happen to the internet, but we moved away from those for better solutions. Solutions that weren't possible without those sites. I am very thankfull that Sourceforge existed. I hosted my first projects there, too.

Good bye and please stop crying like a baby about the hate you are getting. You have two options: make your site as easy to use as github or continue dying. Crying publicly is none of those :) .
