I wrote an article about this yesterday.

There is no way, even if Zuckerberg wants to decentralize, that the big banks who hold his stock will allow it. Marky Mark has a unique structure with FB in that he doesnt own the majority of the stock but his voting power overrules all. So he is free to do what he wants.

However, the bankers are free to dump his stock if he goes awry. Decentralizing is going to cut into the profits which will not sit well with them. Since they own more than 30% of the stock, their selling would collapse the price.

I would applaud FB if they truly decentralized and introduced 2 billion people to cryptocurrency.

Yet I do not see it happening. The FB token will be nothing more than a controlled database.
