As said in the other thread: The joystick has been a most notable design flaw in the first place.
First off, joysticks mainly serve two purposes:
1) Allowing you to move in any direction seamlessly. Up and down, left and right, diagonally and anything in between. The Helix joystick is only allowing for up/down and left/right movements.
2) Allowing you to move seamlessly at pretty much any speed. The Helix joystick is still only allowing for stepwise movements, hence navigating from one end of the screen to the other is still requiring multiple clicks.
In addition, the Helix joystick (or rather: it's mount, whatever that might look like) has to stand movements in 7 (!) directions: Left, right, up, down, turn left, turn right, press. Usually, this is the kind of powers you'd apply when you wanted to, say, losen a rotten screw - so it's almost like maximizing the "let's try to rip it out" thing.
For anything to stand that kind of stress testing for a long period of time, you usually want military grade components. And the Helix joystick absolutely doesn't qualify as military grade. Given my personal experience and what I've been reading over the years, I'd say it's rather located on the cheap-ish side of things, at least the feel gets pretty sloppy after a rather short while, even if you try to not use it too much. And while I haven't been a victim myself, I know of plenty of folks who had to have their joysticks replaced (or at least re-soldered).
And then consider that the joystick could easily be replaced by a simple rotary encoder (with an added press-to-select-switch) and four arrow keys around it. Kinda like Boss (or also Zoom) style. Pretty much standard components that can a) be serviced easily (did that quite often on various devices) or b) be replaced without hassle.
