Some quantom cryptography can work but it's very iffy and expensive, there are ways to detect taps and even when a cable is bent. Simply cutting the connection because the signal was interupted won't work, not to mention that many taps can be inserted without interruption and it's not like the NSA can't figure out how to work around maintenance windows. But in this case it's not even a covert unauthorized tap it's a Chinese company ofc they'll cooperate with the Chinese government. But again encryption doesn't prevent physical attacks of this sort they can still suck all the data out and while it maybe useless unless they can decrypt it this vector has nothing to do with building a secure internet. The problem is that even if you encrypt everything state actors can simply go one step up the chain at the end of the day someone needs to be able to decrypt your packets besides you.
