Barcelona fan groups have accused the club of selling out after not being allowed to attend recent fixtures at Estadi Olimpic Lluis Companys.
Barca first closed a section at their temporary home crowd for the Champions League clash with Brest, alleging an agreement with the Espai d'Animacio - the singing section in the North Goal stand - had been disregarded.
The club claim unpaid fines totalling €21,000 for chants and behaviour inside the stadium had not been paid by the EDA as per their agreement, though supporters have insisted the indiscretions are individual actions and the collective should not be punished as a result.
After fan groups were once again barred from the 2-1 defeat to Las Palmas on the club's 125th anniversary on Saturday, the EDA has accused Barca of "playing" with the team's "dignity" and "history".
A statement reads: "After decades supporting the club through its best and, above all, worst moments, home and away, they have prevented us from celebrating and enjoying our 125th anniversary.

"This is not about fines we don't want to pay, there is much more in the background. Little by little, the socios [members] are losing the weight they have historically had.
"The club are removing the atmosphere, filling the stadium with tourists, Mexican waves at 0-0, 'kiss cams', a joke of an announcer, indecent prices, fomenting the absence of rivalries, changing colours for marketing purposes and taking big decisions without any transparency or consultation."
The stand was in use for Saturday's defeat, with seats re-sold to other supporters.
The statement continues: "There are infinite reasons that reveal the intentions of the board, prioritising a business model where those closest and most loyal to the club are harmed. They are selling the club economically and socially.
"The closing of our section, the voice of the stadium, is the next step in the social death of the club. Either we react or they will end up destroying the most important thing this club has.
"You don't play with the club's dignity. Or with the club's history. And especially not with the value of the badge and the feeling of the socios and fans."
