the left joycon on my switch started drifting after a couple of years, meanwhile the gamecube controller ive had and used for about 20 years still works perfectly

I’ve had my Switch since launch and haven’t had any drifting issues. My brothers both had it though, so I think I’ve just been incredibly lucky.

For me the issue was much worse than drift. One of my joy-cons, that were not really used all that much so the “abusing your controllers” would just be false, just decided that it didn’t want to work on the Y axis any more, and the quick fix was the add some credit card thick cardboard behind the joystick box. The controllers were just really badly made in the first place.

That’s really not the case, my switch got very light use (like a couple of hours a month) and after about 14 months it started drifting.
