It allows freebsd to be true to the BSD license, and I agree with the author that it makes licensing easier. BSD will always be free and incredibly permissive, and I don't see this changing anything. But a lot of the strides that linux has made is because people need to release their changes.

BSD on the other hand doesn't require giving back, so you get Apple that was the largest company in the world building off of the work of FreeBSD. I certainly don't see FreeBSD being comparable to macOS like Fedora is to RHEL. It's more like Apple took what they wanted and walked away.
