That's not how it is. It helps to read official announcements, before implying wrong things.
FC Barcelona hereby announces that, as of today, the Espai d'Animació (Animation Space, EDA) at the Estadi Olimpic, Montjuïc, has been suspended due to the failure of its member groups to heed certain obligations they had agreed upon with the club.

In short, the animation section signed papers with the club. Despite this, they continued to act against these obligations and accumulated fines for 21.000€, despite the club warning and reminding them several times.
Laporta is responsible to look out for the club's interests and if you have a section, that doesn't care for rules they've signed themselves, then it's his duty to change that attitude.
If they deliberately behaved in a way, that the club is fined, then it is more than fair to give the bill back to them. If they pay it, they can come in again, as the club announced. Simple house rules, you break them you pay or get the fuck out. There are enough fans who would love to take over that curve, maybe even more passionate ones.
