From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

So basically, everybody switched from expensive UNIX™ to cheap "unix"-in-all-but-trademark-certification once it became feasible, and otherwise nothing has changed in 30 years.
Except this time the Unix-like took 100% of the market
Was too clear this thing is just better
BSD is mostly Unix too, so even if Unix didn't have 100% because of mac and Windows it was like 99%
BSD is more UNIX than Linux is, to be fair.
BSD is based on Unix, and Linux isn't, so it is way more Unix than Linux is.
