Yes, it is very user orientated. Offering users free software with access to sources for those which are interested. And well, for a lot of software that just makes sense. Maybe not for the kernel or for web-development, but a lot for typical desktop software. SF isn't just about source-hosting, it's about hosting complete projects including distribution of binary packages, allowing that projects use custom homepages (instead of scary source-browsing...) and even support for user (and developer) forums.

I don't think it's that hard to see that this is still preferable for many projects.
