alt Hacker Newsthe US does not mandate spying with roombas -- wtf are you smoking?
China absolutely shares info with all of its national police services, intelligence services, and military. Depending on the company these PLA may literally own some / most / all of the organization.
I am not in the US or China, and on balance I am less worried about the Chinese blowing my house up, but don't pretend they're nice, or that they're your friend. I don't want them having my data any more than I want the NSA, Research & Analysis Wing, or the NK Reconnaissance General Bureau.
You have the Stored Communications Act, the Patriot Act, the Cloud Act, FISA, and so on. Most of which don't require warrants if it is about non-citizens. Which is then shared, through Five Eyes and similar agreements, with foreign countries, so a workaround for not needing warrants in the target country. This is what I commented about, data sharing with the services in my country. Of course Chinese intelligence agencies will share info with the Chinese police, but they don't share with police in the EU.
Again, the root problem of course is that there is any data to share in the first place.
