Good question, can't think of a logical reason.
@Loki knows?
Well, the official statement from the club said they closed the entire sector, because the grada animation failed to meet their obligations up to three different deadlines. This sector isn't a normal one, but has a contract with the club. They sign some rules and obligations to support the team and behave in a certain way, that doesn't harm the club, in return they get discounted season tickets, no one else gets.
So I guess it's a mix between deliberate sanctions, but also to keep this sector open for them to return anytime, if they meet their obligations. Or for other groups as well, if the club finds new ultras willing to take over the sector. Shouldn't be too difficult, as the grada is very small in comparison to other clubs, like 500 people?
Filling this sector with normal fans could make the impression, the club wants to get rid of them entirely and maybe they don't want fans to think that, because it would hurt Laporta obviously.
It's hard to tell the real reason, because the club remains silent on this topic apart from the official statement a year ago and a short notice in summer, that they speak with other groups as well.
Espai d'Animació (EDA) at the Estadi Olimpic suspended due to non-compliance by member groups with certain obligations agreed upon with the Club.

This is also something I blame Laporta for. A year has passed and the club wasn't able to either find a solution with the current grada animation or find a new group. At the montjuic it didn't matter much, but back in the Camp Nou it starts to hurt us obviously, although we won all 3 home games so far. I just hope Laporta pushes the issue up in the priority queue.
