Installing a fan negatively impacts the passive cooling ability (at the absolute least by taking space that could be occupied by a bigger radiator and by obstructing the airflow), so it’s always a tradeoff.
Apple wanted to make it passively cooled, and it wouldn’t be possible at decent loads if a fan would be installed alongside passive cooler.
Macbooks are significantly slimmer, and have way less internal space that could be used to make a combined cooling system that would be passive most of the time.

I have a 2021 Asus Zephyrus G14 unless I run a game, that thing is running without active cooling. Seems like a solved problem.
Solved for larger laptops.

The G14 is 14 inch and has a dedicated GPU, so without one the cooling requirements are far less.
