Soo..
Do these (presumed) state-backed operators need this data in order to fight terrorism and keep us all safe? Because that is (as far as I understand these things) the reason why our own state usually mounts cyberattacks and conduct espionage against its own people)... Is China and Russia just trying to protect us all as well?
Joking aside, I know that the various UK security services are probably less likely to abuse my, yours, and any UK company data that they somehow obtain (meaning using the data outside of their stated purpose of obtaining such data - like building a competing company or product), but the foreign agencies are probably less likely to come knocking on your door in the middle of the night.
So on the whole, I'm not 100% sure who'd I'd rather be cyberattacked by.
