sourceforge was like a big klunky 8-track tape player of open source hosting. it was awful, and it's all there was. literally anything that people put up and managed to publicize a bit would have replaced it. a more interesting question is why did Github win out over Bitbucket (I know the answer to this also, it begins with Mercurial and ends with "Atlassian buys them", but in the middle it gets into interesting questions about source control systems, issue trackers, etc).
