Some personal thoughts about it...
 
Free software is not Open Source software, and Open Source software is not free software.
BUT! Open Source software should be for free!
 
The aim of SourceForge is to offer free Open Source software, and it is my aim too!
 
I'm using openSUSE Linux and WinXP. And I'm using free software that I found here on SourceForge. So I decided to publish my aiPoTT here at SourceForge too. For me it's like giving and taking. And it makes me a bit proud when I see that people download my software.
 
Open Source thinking also offers a great benefit.
When ten people gather together and each offers one product, everyone gets nine products from the others.
