I guess I was speaking as an American, we have good domestically hosted options so although it’s probably not ideal to send this kind of data/control anywhere at all, it’s definitely a worse option for us to send it to china vs to an American company. Every user of this service has made their machines trivially exposed to become a botnet. Im wondering why I don’t see this angle more discussed in here.
Again I’m not saying you should trust an American company necessarily more than a Chinese one, but as an American, I probably can.
As an American you should probably not trust them, because the giant American company has way more (legal or semi-legal) opportunities to manipulate your life than a Chinese one.
On the other hand, an American company can sell your chats to adtech/insurance/your government in ways that can harm you quite directly. Something worth considering.
