I hate how right you are. I do my best to stay out of the Facebook ecosystem (although I am sure they have an extensive profile of my web activities). I am surprised they have not tried to make their own non-crypto financial system. Could embed it into restaurant storefronts and the marketplace.
Meta does not have the support of legislators. The EU would regulate any service that would even aspire to become a Western WeChat way before they have any chance to succeed.
WeChat is so much more than just a messaging app. This is a common misconception when comparing WeChat and Whatsapp. The functionality of those two is not even remotely comparable.
That claim does not ring true to me. Maybe a few years ago, but now? I don't use whatsapp and I don't know anyone who uses it, except for a group of expats from South America who probably use it because it's still widespread in South America and their friends use it, maybe?
