I'm not a big fan of champion hill when it's too busy so I've stopped going along to most Saturday home games. Can't move around, queues are too long, and too many people there don't have a clue about the culture and history of the club so the rabble is diluted to almost nothing.
However, I've no idea how you think the ownership of the club is responsible for that. As others have said, it is partly the community work done by Mishi & others, partly word of mouth, and partly the exciting final years in this Isthmian that have meant the club grew too big too quickly in the last couple years. Do I think games would be more enjoyable if there were a 2k cap on attendances and fans were only let in if they were able to answer questions on the door about the first XI who played in the playoff final defeat at East Thurrock? Yes. Do I think that should happen? Absolutely not.
I'm not sure what powers you think Ben has to make home games more enjoyable.
