I always wonder what might be the reason of centralised authorities not accepting the power of Decentralization and then found the reason,if so decentralization becomes the only means for the transactions then most of the regulators and authorities might be jobless and so they are putting maximum to let down this technology by creating a hype that all the crypto currencies are scam and you can making nothing out of them investing,so we Crypto enthusiasts need to put our maximum efforts to empower decentralization .
Well, blockchain technologies are well accepted for governments, it's integrating in a lot of services, both from governments (for example land registry) and from commercial/non commercial organizations. Walmart is integrating BC technologies and etc, read articles on cointelegraph.
And government don't like crypto because they can't control it, this is not so hard to understand.
