Don't mistake fantasy for intuition.
Although his points are exaggerated, there's quite a lot of things there which are not fantasy.
This ESPN article shares the same views that Messi is pulling the strings in the team behind closed doors, in conjunction with his veteran friends. You couple this article with live video vs Celta showing Messi flat out disrespecting the managers publicly... and there's a lot that makes sense there. Sure, if you're a fan of Messi the person, you can disregard all of that.

So, it's perfectly fine if people think Messi doesn't do that. But there's a lot that suggests he does as well.
Also, it's illogical if you think Amigos run the club, but spare Messi of major blame in this. If you think Amigos run the club and they use their seniority to influence things that are above their profession, then you have to follow through and be against Messi just by principle alone. There's no Amigos without Messi. Messi is Amigo no1. The worst things in the team can be seen with Messi: veterans stepping outside their boundaries, laziness, improper discipline, protecting soft managers, you name it. People act as if these are fine because he is great at playing football. But they're not.
