There is a difference between CCC being ambivalent at best, and them actively working against the club, however.
Now, if we do indeed go backwards, it was ultimately Dave Nellist who iniststed that any Ricoh deal involved commitments to regeneration of the surrounding area, before he signed up to it (the Ricoh deal was campaigned for by the club btw, McGinnity was very forward in being proactive in encouraging that deal to be made, to divest the club of their responsibilities to build it) and that has, arguably, handicapped the stadium being seen as just a sports stadium from that point on.
When we come to ACL, we should probably target national government rather than local government. Local government has been made to pay its way more and more, both in commercially justifying their actions, and in having funding withdrawn. As far as I am aware, CCC is not one of the better off councils and doesn't have the cash to throw around. Therefore, any deal (and remember, the club pushed for the deal) would have to make it pay its way.
At that stage, we get this horrible crunch, where the interests of ACL don't marry the interests of CCFC. That's still kept in check while CCFC owned half of ACL but... that didn't last long!
So it's certainly not working against the club to begin with (the directors did a fine job in that by themselves!), but it does end up financially straightjacketed. Elements such as stadium branding etc. yes, I would argue we have an intransigent council, but McGinnity had taken all the stuff about the cup winners down at Highfield Road - they weren't alone in being shit in realising the emotional connection of the club.
Fast forward to SISU, and it seems relations were actually OK between most parties involved. The personal stuff seemed to be agitated by Seppala and Mutton seemingly not getting on, and having vastly differing perspectives. It must have been very hard for Seppala, a ruthless businesswoman who makes decisions swiftly, to understand a council that drags its feet as much through following the process it has to follow. Likewise, Mutton's comments about SISU were deeply unhelpful, and they badly needed some empathy about how, ultimately, SISU were a business who didn't need to have that emotional connection of fan and then yes, things broke down, seemingly irrevocably.
To get where we ended up, where every single member of the council voted for the Wasps deal, regardless of party allegiance, is... unprecedented (to borrow a Covid trendy word!) really. usually you have one or two rogues who see either an opporunity to make a name on being different, or because they can get something for themselves and / or their ward. That's not really a council conspiracy, and *something* in that deal made it important to be passed. i'd assume the main thing is transferring risk onto Wasps, rather than the council, tbh, and allowing CCC therefore to budget with less constraints.
It's safe to say (as, well, it's been for the past half a dozen years plus
) that none of the parties cover themselves in glory with their attitude. Current events don't change that really, they just continue along the same lines...
