Perhaps it’s true that less dirt gets under butterfly switched-keys. But therein lies the problem — when dirt does get in, it cannot get out. A piece of dust is capable of rendering a butterfly switch nonfunctional. The key won’t click, and it won’t register whatever command it’s supposed to be typing. It’s effectively dead until someone can either shake loose the debris trapped under it or blow at the upside-down keyboard Nintendo-cartridge style. Meanwhile, Apple quietly put up a page with instructions expressly to try and help people with dead butterfly switch keys.
The problem with dead keys is that, unless you can stop what you’re doing mid-paper or report or email or game and have a physical tiff with your computer, the temptation to just slam a little harder on those delicate keys to get the N or B or period you need until you reach a stopping place is high. But there is no logical at-home remedy for the consumer; when one key on a butterfly switched-keyboard becomes nonfunctional, unless you can dislodge whatever dust or crumb is messing it up without being able to physically access it, the keyboard is effectively broken. If you remove the key to try and clean under it, you stand a high chance of breaking it permanently, but if you leave it there and continue to have to pound the key to type one measly letter, you also might break it permanently. A single piece of dust can literally fuck you over.
My 2016 MacBook Pro Escape keys like to get sticky when I’m hammering away at the keyboard in the sun, probably due to the key caps expanding from the heat.
This is bad design.
