It looks like someone is a little bu.tt hurt in addition to not being particularly smart or knowledgeable.
The penalties against Saudi Arabia, Netherlands and Croatia are technically correct.

Croatia: already provided evidence in previous post, but in summary it's a blatant penalty: the goalkeeper deliberately extends his leg opposite to the direction of the ball (which he MISSES) in order to put himself in the way of Julian Álvarez's path, preventing him from continuing the play. Some people seem to be trying to apply basketball logic to a football match.
The only one I do not agree with is the one in the Poland game, which even though it's defensible (the keeper misses the ball and hits Messi in the head) it was a fraction of a second too late to be considered a foul. But that penalty was missed and thus had no bearing on the outcome of the game, so it's a moot point.
If the Saudis, Dutch or Croats tried to gain unfair advantage and not being punished as a result is beyond our control, the only thing we can do is wait for the ref to do the right thing (which they did) and punish them accordingly within the rules.
Concerning the match vs Netherlands, Messi arguably should have received a yellow card by the deliberate handball but that would have been his first, anyone saying that since he received another one later on it would have meant he'd be sent off, has trouble grasping that future events are not independent of past ones. When a player is booked he's usually extra cautious, and 20 years worth of evidence suggests he wouldn't have received another one for complaining.
As for Paredes, he's looking backwards from the ref so as far as he's concerned the ball is in play and he's kicking it out of the court, if he's near the Dutch bench and kicking it out ends with the ball there, there's no rule preventing that. Should Paredes have received a yellow card and be sent off? Maybe, but not before Van Dijk, whose disgraceful assault on Paredes by shoving him to the ground should have been an automatic red card, and you could make a case for several other Dutch players who physically retaliated against the Argentinians.
Calling Messi's celebration near the Dutch bench "harassment" because of an (inherently subjective) interpretation of what he meant by that gesture is an insult to everyone's intelligence and not any more justifiable than the ref who sent Tim off because he was laughing on the bench. That's bias (and stup!dity) speaking.
As for the comments after the match were actually very mild in comparison to, say, Uruguay's reaction in the aftermath of the elimination. In fact Modric also made harsh reference to the officiationg yesterday, as did Pepe with Portugal, and neither suffered consequences other than maybe a financial sanction. So I'm not sure what it is you're expecting here.
Also, there's no mentioned of the ridiculous stoppage time and weak ass foul that forced extra time. Wonder why that is...
So all in all, that's an incomplete, biased and not very intelligent recollection of events designed to draw a conclusion that is surely the result of some dumb a$$hole being bu.tthurt and unable to make a more coherent case.
