I have had it happen to both my right and left Joycon within the past few months. Never happened before then however, and for me recalibrating fixed the issue in both cases.
It definitely seems like more of a wide spread case and hopefully they not only fix the issue for Joycons noving forward, but also have already resolved this for the Lite.
That being said, this kind of thing happens to ALL controllers so I find it funny how quick people are to single out Nintendo. One of my X1 controllers just had the same issue not that long ago, but it could not be fixed by recalibrating and I had to replace it.
I've owned every Nintendo console except the Virtual Boy. I've never had a problem with a controller from normal wear and tear before with them. I've never seen this on a Sony console either, though I don't own a PS4. Can't say much about Microsoft consoles, as I lived with a guy with a 360 back in college and never had issues with his controllers but that's about it for my Microsoft experience. I'm not saying it's a Nintendo problem, I'm saying it's a control stick problem unique to the Switch. I've never seen anything like it. Any other controller I've had or a friend has had that had this problem could be fixed by turning the console off and on again or otherwise recalibrating the controller. All my controllers that I didn't personally break in frustration work, all the way back to the NES.
And while I'm sure your XBO controller did indeed have a similar issue, and I'm sure the occasional controller for other consoles have too, the fact of the matter is that this is a wide scale thing for the Switch, on par with the RROD for the 360, but less devastating. Nintendo really should address it. I love them, but they're being cowards here. I should not have to fix my own controller from normal wear and tear just 6 months into using it. That's a decade plus kind of problem, not something that most people should run into within the normal lifespan of a console.
