Hmmm.. useful piece of information I honestly had no idea about.
But TBVH I don't see how the blockchain can escape their monopolistic powers if these groups do decide to enter the space (or maybe they already are). They may have less influence on the space, but I think they'll have just as large a stake if they please
The stake isn't supported by legislation, meaning you can walk away. Look at the move from Steem to Hive as a micro example of what could happen at scale.
