I think it is far to late for governments or single company to try and shut decentralized block chains down. I know Bill gates tried it with git-hub, by taking control of it and restricting people from using it. After those published and very public attempts, git-lab was created. So the writing was on the wall for attempted control and that writing was over written by the users of block chain technology.

Communities, as has been shown with the steem/hive split are not going to allow themselves to be controlled by one group or one organization. Hive is progressing along pretty well, it will not be long before we transition from community to a society.
