I can't really understand the issue. Analog sticks for gaming devices exist for some 20 years, without much problems. Why are they having these issues now and why are they so unsolvable and persistent now? If it's related to wear - calibration software is not that hard to do. Nintendo had calibration options before in the Nintendo DS touchpad. So why not with the joycon controllers? But tbh. in 2021 there should be even more sophisticated ways, like automatic calibration.
