Totally this. A website isn't even necessary for collaborative development, all you need is git software and a group email!
For issue tracking, you can use something like self-hosted bugzilla (or one of the several free instances out there). And for discussions, there are always things like mailing lists, forums, IRC, social networks, reddit, etc. That's how it used to be in the good old days. I don't understand why one even needs a code hosting facility.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
