Projects like FileZilla, The GIMP, VLC and nmap have been hit with the baddie installers coming from SourceForge, which the company deemed the projects as abandoned. I can understand SourceForge's need for money to sustain their business platform, but the way they are going about doing it not only tarnishes the individual projects, but also makes Windows users have a bad first impression of open source by getting and running the bad installers from SourceForge.
We have found in recent months that even huge companies like Google can't maintain a truly free code distribution platform like their Google Code service, hence why they are shutting it down in the near future. These big named hosting platforms need some way to maintain a revenue stream to support the hardware, bandwidth and management of the various projects they host. I am in no way validating the practice that SourceForge has decided to do.
