I read an article that China used technology to spy on users via their phones (https://www.theguardian.com/us-news/2020/dec/15/revealed-china-suspected-of-spying-on-americans-via-caribbean-phone-networks). 

Here is my white paper analysis.

#1 - If a device has connectivity with at least one other device, it can be,  has been, or will be compromised.

#2 - If a device has the ability for connectivity with at least one other device but isn't connected yet, see #1.

#3 - If a device is airgapped from any other device, it can still be compromised.

#4 - If a device has a speaker, someone you don't know can hear you.

#5 - If a device has a camera, someone you don't know can see you.

#6 - If one nation-state is monitoring your device, probably another one is too (maybe your own government!).

The good news is that criminals are more easily identified, tracked, arrested, charged, convicted, and incarcerated.

The bad news is that every bit of your life is logged somewhere, by multiple entities without your consent or knowledge.
