Conversely, a lot of free software I use on both the desktop and on servers is hosted on GitHub. (I'm not sure how this argument is a rebuttal against GitHub acquiring SourceForge)
Though, GitHub is in the collaboration business. They take the standard git model and remove 99% of the complexity of me trying to share my repo with my co-workers while I'm at a coffee shop and can't passthrough a NAT router, for example. Hosting software is kind of a by-product. SourceForge has always been about software, not collaboration between people. Buying SourceForge wouldn't solve anything since dead software will still be dead software without someone to take the reigns and become a manager of incoming patches and contributing him or herself, which all can be done without spending 20 million.
