Facebook and twitter have been censoring posts related to insurgency in the US and actively pushing ads with false science in them.
They also sell your data to the government to use, so if you live here... you should absolutely trust Chinese software over US software.
You don't know what the US will do with your data either... they use it for a hell of a lot more than advertising.
Data isn't like... a precious metal. It's not like you're giving China more power by giving them your data. There's absolutely nothing they can do with your data that would affect you more than the shit your own gov would do with that data.
