The mining facility is close to a US Air Force Base that houses intercontinental ballistic missiles. No country will want a political and military enemy to be close to such a sensitive facility. The location of this Chinese crypto-mining firm is a security threat to the US because they can easily collect sensitive information or even carry out an attack. My reservation is that didn't the land authority know that MineOne was a Chinese mining firm before the land was allocated to them. Now they are putting pressure on the crypto firm to relocate within 120 days.
Exactly what I was thinking, if there's a possibility that someone might be able to remotely access your nuclear cache and your airbase because they're near that base, there's some level of reasonability as to why this thing should happen. The weather balloon that was actually a spying device should probably be enough answer to this one, China's been upping their espionage game lately so I'm not really sure that we should be too lenient when it comes to this kind of things, better safe than sorry especially with ICBMs caches at stake, I'd rather be paranoid and awesome that everyone's trying to spy on me than be relaxed and then know later that there's someone rogue that's also in control of those world ending weapons.
