I translated a post from a Germany Barca Forum about Tebas, answering a question why Tebas always attacks Barca. I think it hits the nail:
In Javier Tebas's case, his way of leading the league and his political stance are simply inseparable. For someone who happily flaunts his political views and then runs the league exactly as one would expect from someone with those views, any consideration detached from politics would be naive.
It would be as if the Bundesliga president were an AfD (German right-wing party) supporter, and coincidentally, the DFL only ever tries to revoke Türkspor's (Turkish team) license, and the said president also speaks out far beyond his authority regarding what Türkspor can do and what it can do.
Tebas is a Vox supporter. Vox stands for a centralized government and thus the abolition of Catalan autonomy. The exact opposite of what FC Barcelona stands for. Tebas is therefore not just a Real Madrid fan who thinks Barcelona is stupid as a fan. He is someone who considers FC Barcelona a political and ideological problem.
When someone like Tebas comments on a referendum on Catalan independence that it means the exclusion of Catalan clubs from LaLiga, he is stepping outside the purview of a league president.
He is stepping into the realm of a right-wing populist attempting to change the outcome of a political election. Tebas can't (officially) lead LaLiga as a dictator who could make such a decision alone, nor would an exclusion have been as set in stone as he had portrayed it. And even if we enter the fantasy world in which Tabas could have made this statement, he is still playing politics by standing in front of the microphones with this objection.
This sets an important precedent that Tebas is not above exploiting his position as LaLiga boss to push his political ideologies.
But okay, so Tebas just hates Barcelona? I think there are more fundamental ideologies behind it. Tebas has no problem trying to override the courts. He has no problem telling the world that Barcelona can't make any transfers, even though the salary cap doesn't allow it, and in retrospect, it was obviously wrong that summer. In doing so, he's doing exactly what other right-wing populists do as soon as they come to power. Just look at Hungary or the USA for that.
Javier Tebas doesn't want to create a fair framework within which every club can then independently operate. He wants a central government that can intervene in every club and determine exactly who can do what and when. He shouldn't be deterred by pesky courts, not by LaLiga's rules, and certainly not by the opinions of individual clubs.
This is also evident in the fact that, of course, the court ruling is not accepted. And even more absurd is that a large part of the statement revolves around the court's decision to temporarily suspend Olmo and Victor until the matter was resolved in Barcelona's favor. That's simply a shocking and disgusting worldview.
