Hate to break it to you but bill gates can't buy sony at all to but a company u must have a majority share this means that you must buy shares now if he can't find over 50% to buy he can't legally be the sole owner and if people don't want to sell to him they don't have remember money won't buy everything the stock market is there to trade them but in reality only if there is some to trade and well I think the majority of those who own sony shares don't want him to own the company so he can't buy shit boy
