Yeah Apple needs to fix this by either making Xcode Cloud better, make more Mac minis (or just dedicated server hardware), or even loosening the two-VM limit. This kind of thing is bad for the average consumer and just plain wasteful.
Plus, since the desperate are willing to do crazy-looking things like this, bulk-buying $6,000 premium laptops with batteries and screens, at enormous margins, Apple is even more incentivized to keep (not) doing exactly what it's (not) doing.
