i can think of absolutely zero publicly traded company boards of this size that would opt for "we're already selling enough devices, we know there's more demand we can't meet, let's not scale up we're really happy with these numbers"
Due to the RAM shortages, Apple isn't able to meet demand as it is.
Apple's Mac revenue last fiscal year was $33.7 billion. I suspect the number of Linux users that might buy a Mac if it could run Linux natively is probably in rounding error territory.
Apple has been around for 50 years and has a market-cap of around $4 trillion. All without supporting Linux. I think they're okay with that.
