Why would it? Shareholders of the major stocks are generally vibes-based, and I'm sure that if Apple undertook that, they would find a way to build hype around it.
The Mac has never been more popular in its 40 year history than it is now. The recently released MacBook Neo broke all previous Mac sales records. Needing to sell more Macs isn't an issue these days.
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.
