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.
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.
But if you live in an area with little exposure to these communities, I doubt the Chinese government would care about your private information.
But no matter who I am I certainly wouldn't want North Korea to have my private information, because they'd have no qualms about finding ways to use it to empty my bank account.
