It depends on your perspective though: is your license aimed at developers only, or all end users. The GPL makes it quite clear that there's no distinction between them, everyone is an end user who may not restrict another end user. Other more "permissive" licenses can be used to constrain anyone though, because the developer sees the license was only for him, and those permissions are not relevant for his end user.
