You're comparing apples and oranges though- Ubuntu is a distribution that attempts to be a complete desktop OS, and FreeBSD is a single project that provides the kernel plus the required low-level userland of an OS. Complaining that FreeBSD has strict licensing requirements is like complaining that the Linux kernel has strict licensing requirements- they don't, they just have project-wide standards for licensing. Ubuntu (or Linux distros in general, or PC-BSD for that matter) is less of a project and more of a collection of components from different sources, so by definition it's not going to attempt to impose its own licensing requirements on those third parties. Think of it like this: if the Linux kernel project evolved in a different way, such that the project as managed by Linus wasn't just the kernel but also the required low-level userland (libc, /bin/ls, etc.), then you'd end up with something that closely resembles FreeBSD. No one would use this hypothetical "Linux kernel plus low-level userland" project by itself, they would install it and then install whatever else they wanted from other sources on top of it. There would still be all sorts of distros that made it easy to do this. Ubuntu would still exist, except structurally it would more closely resemble the relationship between PC-BSD and FreeBSD.
