I run an eCommerce platform, have some experience of this stuff.

It's also only viable in China because in China, the government, companies, and other such organisations are your friends and you have nothing to hide and they are mother and father and you can trust them completely.

In the west - not so much. People generally distrust governments and organisations, and are much less likely to trust the likes of facebook with eCommerce transactions. People won't even use their social media identity to log onto an eCommerce site (well, 0.02% of people will) - so the idea of them buying through a social media platform is fanciful in this observer's mind.

I may well be wrong, but unless there's a major shift in observed consumer behaviour, this isn't a thing outside of those corners of the world that explicitly trust all authorities.

FWIW, I think there's a big difference when the directions are reversed (although that may not be rational).

Example: Log into amazon site with facebook credentials? Hell no. Make amazon purchase through facebook chat bot? Possibly.

When it comes to commercial trust, all third parties are not equal.

You don't have the option to log into Amazon with Facebook or any other such service. I think Amazon are quite happy keeping their customer information to themselves.

Amazon and Facebook actually partnered in Facebook's early days. Purchases on Amazon would automatically show up in users' news feeds. Headlines at the time were full of things such as "Facebook ruins Christmas" and the like.
