Agree entirely. SourceForge is unfortunately one of those places that puts me off projects these days. It's a baron land of advertising and poorly maintained products that just add noise.
I thought that SourceForge was a barren land years ago, at least ever since they started putting interstitial ads in the downloads.
As someone who sits in front of Windows but does a lot of development over ssh in Unix this is slap in the face. There are both manual and automatic ways to get the real url that you could type into axel, curl or wget, but it just shows a lack of respect for customers.
I made a point to keep open source projects away from sourceforge because it was a ghetto, the same reason I didn't want to be seen on myspace. Just knowing a project is on sourceforge would bias me to think the project is not worth thinking about.
