It isn't hard to create an arbitrary set of constraints to single out a single laptop. Just because some laptop has a fan, which is often a complete non-issue in non-Apple laptops (Apple's laptop fans in the models that have them are some of the loudest I've experienced), doesn't mean that it doesn't compete and that there aren't tradeffs. For example, Apple laptops are extremely uncomfortable on your actual laptop due to how hot they get.

How is that not a problem when it is?

I want completely silent laptop that doesn’t get dust inside of it.

It's a tradeoff, not a problem. My XPS has fans and is silent except when doing something very intensive, like gaming, which macOS is terrible at if a game is even available for it. If the XPS gets dusty, which it hasn't so far, then I can easily clean it by removing the back panel since the XPS is made to be repaired and even upgraded. So if you truly want a fanless laptop, then it looks like the Air is the main contender, but then you have to use macOS and the other downsides of a Macbook. Microsoft makes fanless laptops, but those are the Surface Pros, with their own set of tradeoffs. The Surface Laptops do have fans. For me personally, whether a laptop has a fan or not is pretty immaterial. So like I said, it's a collection of tradeoffs and personal preferences.

And please note the original quote that I responded to. They referenced all Apple laptops with the M1 and later chips.
