Good point that it's unlikely to be as simple as a $500m return but regardless of the amounts or structure of IPO my question was more around who are the existing share holders of the commercial company? Is it the foundation or someone/something else? Is this float to get cash or financial stability for the foundation or a cashout by other parties? At the end of the day I'm not going to be too critical in any case as I've contributed nothing beyond buying a few boards and making a few posts in support!
