I think that's exactly the point and it even applies to Macbooks: Apple just makes some pretty average laptops with poor price-performance ratio (even in the allegedly-high-end segment) and they clearly don't have a monopoly or even significant market share [1] in that category. Apple is just somewhat unique in that there is a very vocal minority of people who have decided that they only ever want to use Apple laptops (some Thinkpad users are similar), and of course Apple has a 100 % monopoly on Apple laptops, obviously. Viewed through this lens a lot of the coverage of Mac hardware makes a lot more sense; it never was about rational decision making.
[1] Apple owns less than 10 % of the laptop market.
