Joysticks: Probably Still Drifty
Joy-Con joysticks use a potentiometer to read the voltage at a wiper that slides across a strip of resistive material. That material wears down over time, or plastic and dust can dirty the sensors.
Stick drift is a huge problem with other Switch models. One survey found that 40% of Switch owners had problems with their Joy-Cons drifting, and things didn’t get any better with the Lite or OLED editions. After a bunch of lawsuits, Nintendo’s president even admitted it and apologized, setting up a free repair program for customers in some parts of the world.
Why fix something that is making you even more money?!
But the invisible hand!
Exactly this. Lots of companies have figured out that filling our landfills with cheap plastic crap is a lucrative business model. In this case, it’s cheaply made and expensive to replace - making it hugely profitable. Shareholders would be furious if they were to fix this issue.
