He can't!
He must use anything.... anything to denigrate this sim, it's his mission.
It doesn't matter that he presents himself in a less than favorable light
by presenting such "very important facts" like the missing ground loop.
That fits seamless with his exaggerations.

This sim has its faults, no denying that, but they've been presented again and again and again -> boooring.
The devs are working to solve the problems, and maybe, just maybe, when the important things are solved, the "oh so, very important"
ground-loop will be implemented.

Instead of trying to pull something down (always the easier part), one should strive to build something,
and be it the good reputation of a sim.
