It all depends on the perspective. Governments cannot control crypto directly since they are not the one who developed it.
They don't any access over the specific blockchain network. What they can do though is that they can restrict the company from operating in that locality.
But still the company has the option to operate the network from countries which are crypto friendly.
So yeah, Government cannot control crypto directly.
Technically speaking no governments or no one in this world that a country government have a control over a cryptocurrency. But know what the things that the government has a control over crypto? It is the laws and regulation on their government like prohibiting their people to use or invest in crypto and banning cryptocurrency to be circulated in their economy, but directly having a control over crypto market it is absurd and unbelievable to be exact.
