> How would you feel if Roomba devices were controlled by North Korea, for example?
Depends on where you live. If you are living in North Korea and somehow you got to own a Roomba, it would be surely a bad thing.
But living in a western country, I would hands down prefer giving all my secrets to the North Korean government instead of my own one.
Yeah, this is the funny thing about it.
As an American, I'd much rather a Chinese company have data on me than an American one.
The American government and FBI and police don't have access to the Chinese company's data. But with a subpoena (and sometimes just with a friendly ask), they sure do have access to an American company's data.
Now if the US is at war with China and you're a politician or in the military, then of course get rid of every device in your home and workplace from China that could be used to spy. But if you're just a normal citizen worried about your government collecting information on you, it seems preferable to stick to foreign companies, like Chinese ones.
