Why would there be expectation they'd do anything more for Linux?
Linux is more complementary, compared to Windows which has been an existential threat to the Mac since the 90s.
I agree with an earlier comment: I don't expect Apple will provide any assistance, but neither do I see it as entirely unlikely.
This also enabled those users to spend time in MacOS or switch to virtualizing Windows and may lead to one or more personal purchases for themselves or members of their household.
And one of those core services is the App Store.
It's already at the point where macOS will treat apps as if they're radioactive if the developer didn't pay the $100 Apple tax before distributing it.
