Intent doesn't matter at all, so not sure why that would be brought up.
If the ref deemed that Suarez, in possession of the ball, was running in a normal way and then the defender slide in and put his foot beneath Suarez' (where he was going to land), then that's a foul on the defender. If the referee said to VAR that's what he saw, then there's nothing for VAR to overturn as it's a judgement call. I think it's a ridiculous judgement, but that's still within the refs realm of control.
If the ref told the VAR guys that he thought the defender went studs into Suarez ankle, then that's something for VAR to review.
Either way, I'm not (and really no one is) arguing that VAR is absolutely perfect. We're just saying that it's not some giant conspiracy meant to hurt French teams that's somehow been given as instructions to all of the VAR refs and field officials but magically has never made it into the public.
"VAR made a mistake" <---- perfectly fine point
"UEFA is secretly (but also super publicly and high profile) trying to screw over every French team because PSG cheated, but they haven't done it in any number of ways that would be super easy despite chances being there, they've done it by leaving the fixes as late as possible" <--- That's a ridiculous point and why people are commenting about it.
