Anodising is thinner or poorer quality and it wears where the greatest load is which may indicate that something with the design is nqr and needs a design tweak or solution in the future models. I've seen a few that have these wear marks in 2017 on shocks. 40hr shock oil changes and keeping the bushes serviced or replaced frequently is the best solution.
After a while the shock tube will need replacing and thankfully they aren't to expensive (less then $200) although it shouldn't do this so quickly.

I got rid of the heim joint and replaced it with a bushing that I had made up from a nylon-like material. Canít quite remember the name of this stuff at the minute, but it has very good wear properties and is self lubricating from memory. Anyway, I bought a length of cylindrical stock and had it machined for bugger all and got a half dozen out of it. They easily last 3 or 4 times longer than the heim joint ever did.

If the Heim joint can be swapped left to right by turning your shock 180 degrees... that might fix it.
As a Mechanic; if a car pulled to one side; I'd swap the front tyres thus reversing the bias-straight.

As I meant to post; skewiff becomes more skewiff; swapping evens the Yin & yang of the Universe.
That might work; eventually bias will kick it the other way again; by then your Heim joint is stuffed.

Regardless; something is out of alignment/parallel to cause such-wear on a new bike:
It has to/do with force acting from the top to the bottom, likely-merely ~1/2mm out.

My thoughts are that the bolt-hole through the Heim joint isn't parallel & horizontal:
Or-that the swingarm itself isn't parallel to that/which frame/mount, as it should be.

Yeah, I think thatís it. It goes good in that application, and because itís a full width bushing the load is spread across a wider area so it doesnít wear as quick. And vesconite being quite hard means the centre hole doesnít oval out very easily as would a softer material such as nylon.
