> A similar situation occurred with Minix - to the extent that it's creator Andrew Tannenbaum had no idea it's install base was arguably bigger than Linux until 2017. Intel had put Minix into the Management Engine on their professional grade CPUs for years. The BSD license allowed Intel to put it everywhere without the knowledge of the wider Minix community.

Off topic question, but wasn't that a violation of the BSD license? It does require a copyright notice.
