That may be true.

And the Linux kernel is rarely forked and usually only temporarily.

But within the past decade, the BSD operating systems have only been
forked a few times successfully, while Linux-based operating systems
continue to be created (including Puget Sound Technology's upcoming Linux
distro).

As for individual software, BSD-licensed code is sometimes forked.
(Examples include the man and netstd/netkit derivatives used in Linux
distros.)  And many GPL'd projects continue to be forked.

I guess the distinction is not whether it is really commercial or not, but
if an end-product became entirely proprietary. Any examples?

Anyways, where is the detailed list of technologies (intellectual
property) that was used?

I would like to compare with the old 4.4BSD-Lite which I still look at.
