A Canonical employee releasing a wrapper to download and run unlicensed MacOS, and shipping it via Ubuntu's explicitly for-profit app store? There is noooo way this was approved
"Sofireme" seems way more appropriate, or maybe "Sosumyemployer"

As pointed out in the other comments here, the EULA definitely allows you to run macOS in Ubuntu if you're using Apple's hardware.
Pretty sure the EULA does not cover copying essentially a DRM key from the SMC and checking it into GitHub, conveniently set up in such a way as the repo does not in fact require Mac hardware
The "secret" Apple OSK string is widely available on the Internet. It is also included in a public court document available here. I am not a lawyer but it seems that Apple's attempt(s) to get the OSK string treated as a trade secret did not work out. Due to these reasons, the OSK string is freely included in this repository.
That repo has been around for many years.
