This is definitely not legal, but the fact that the apple ecosysten is still stuck in the pre-vm era in 2020 for the purely stupid business model of jailling developers in an apple ecosystem as soon as they need to create an ios app (which should never require an apple computer in the first place) is an absolute ridiculous waste of time and resources.
Any company that deals with cross platform products has to build a modern CI/CD and a medieval stuff on the side to deal with apple.
Enterprises have two choices: a closet full of mac minis (or similar) or violating the letter (but not necessarily the spirit) of the EULA. At the last Big Tech Company You've Definitely Heard Of I worked at, our Mac build farm was deemed noncompliant by everyone including Apple and our legal team, but nobody actually told us to stop using it. Quite the opposite actually.
The problem is that there is no way to run proper infrastructure that involves Macs since removal of Xserve platform, and even that wasn't particularly great when it came to lights out operation from what I heard.
Even if you pay ridiculous amounts of money for latest Mac Pro in a rack, it's stil the kind of joke machine that I chortled over in 2008 for being the cause for crash carts to be present in server room, when every serious machine had you in the comfort of nice office.

Sorry for the rant, just had to get this out.
