Going by the conversations I've had on Facebook, most of those shouting for the deal to go through are neither Well Society members nor shareholders. They truly believe the Society's been running the club for years and it's getting the blame for everything the Executive Board has/hasn't done.
If he's a shareholder (if), potential conflict of interest? Maybe he could but chose not to, which is his right. Would you be happy for him to very publicly back a yes or no vote if it differed from your opinion?
