The club had access to the revenue streams via the half-share in ACL. The one that they had to sell to the AEHC because they were going bust.
The one that SISU didn't bother trying to buy back until years after they'd arrived on the scene, and even then on buy-now, pay-later terms. If it was so key to the club, why did it take them so long, one wonders.
Once again, forgive me, but it seems you're blaming the Council for the club's failures. The Council didn't force them to sell their share in ACL, or even stop them buying it back. Anyway, I'll lay off mate, you can come to your own conclusions...
