I hope they don't stop repairing joycons. I have had 3 repaired (one for drift, two others for button repairs. All free of charge. My expierence with them has been amazing.
Also i had bought a Monster Hunter joycon from a "retro" store, and thought they were legit as it had the same paint job with symbols, and felt and played like the official joycons, even had the same nfc scanner ,(most 3rd party cons don't have that), vibration, etc... The "A" button started not responding properly. You had to press directly in the middle or upper part of the button or it wouldn't register on the first press. Sometimes you had to hit a twice to get it to register. So I sent it in to Nintendo. They wrote me back saying it was "counterfeit". I didn't notice no branding on the back.
They sent the controller back unfixed, but to my surprise the issues with the "A" button were gone. Not sure if I got a tech who liked fixing things but my counterfit joycon was now working good as new.
Now this sort of thing shouldn't happen in the first place, but if it does, its nice to know Nintendo has your back with issues like this.
If no lawsuits though, I don't know if they will continue this policy.
PS4 controllers were worse with drift, imo.
