I'm not dismissing anything, just pointing out two things.
1. You were outright wrong about brakes.
2. If you're concerned enough about tyre wear to single it out then you really are clutching at straws.
From your own link:"My personal experience has shown that EVs require A LOT less money to maintain than gas cars.
This is true for everything — except when it comes to tires!"
So for whatever reason that guy is having issues with tyres.
Now I don't doubt that, but nobody ever complains that diesels are heavier on tyres despite usually weighing significantly more than the petrol, so why are EV's singled out?
A quick look suggests EV's aren't much if anything heavier than a diesel equivalent.
Further down he mentions he had to buy a new set of tyres on his Leaf at 40k miles - if that's true he's doing better than me on my 1250Kg petrol car (and they run me £600 a set!).
So you (and him) seem to have assumed it's all about weight.
Now unless diesels also have the same problem I'm going to say you're both wrong and instead suggest the real culprit is acceleration.
EV's are significantly nippier than petrol and diesel equivalents by virtue of a lot more torque and nothing wears tyres faster than accelerating off the line.
He does admit to a bit of a heavy right foot too which furthers my suspicions.
Fortunately there's an easy fix. Leave the car in eco mode and keep the right foot light.
