The less info about you is out there, the less handles they have to pass themselves for those who can legitimatelly ask money from you or which control access to your money, be they family, friends, your bank, the government and so on.

They can't spoof a family member's voice if they don't know who is your family or have access to samples of their voice - both things often obtainable via Facebook and would also be obtainable via a Chinese equivalent one might be tempted to use instead.

Anyways, my point is that Chinese companies are inherently no more trustworthy than American ones, they're just not as bad yet because they don't yet have the same access to masses and masses of personal information for people all over the World - once they do, they'll be just as bad because regulations in China are also shit and they don't give a damn about foreigners.
