Thanks a lot for the video. It was super informative and a gives us important information about a very big issue. This explains why stick drift happens accross the board, because Sony, MSoft, Nintendo, all use the same parts for their joystick.
It probably isn't a secret to anyone that all the console manufacturers make a lot of money with selling joysticks. It's especially important for Sony and Microsoft, who often sell their consoles at a loss during the first few years. However, some console generations ago, joystick drift wasn't that prevalent. I think it started when Sony cheaped out on the Dual Shock 4 to keep manufacturing cost down and therefore even make more profit with their controllers.
I mean, a first party controller has never been cheap, but at least in the past, when you bought a dual shock 1, 2, 3, Nintendo controllers in general (yes, I know the N64 stick was shit, but that was due to the technology being so new) and Xbox controllers, you knew, they were of great quality (which they actually were).
But in recent years, we've seen a trend of cheaping out with what's probably the most important device for any console, that also get's the most use - the controller.
All the big console manufacturers REALLY need to get their shit together and fix that issue in the future.
