This articles title seems a bit of a witch-hunt. It does say in the body of the article that the mechanism is the same used for Nintendo and many Microsoft controllers so this isn’t a Sony problem so why only call out the PS5? Click bait?
A question that should be asked is why don’t they use hall sensors instead of a design based on potentiometera. They are all effectively building controllers that by design will need replacing several times in the lifetime of the average console and gamer. It seems by design they are deliberately choosing a design that won’t last, obviously to make more money on accessories while creating more waste.
