Isn't that what any other payment system and most of the banks around the world are - a foreign company with billions of dollars in charge of payment system in a country.

VISA, Mastercard, HSBC, UnionPay, ICBC, Santander... Or is this all Brazilian technology?

The difference is that Meta is privacy data hoarder, not that it's a foreign company. And it's not "in charge of countries payment system", because that's pretty-much impossible, but "one of the payment systems in the country".

That's why China created UnionPay, so it wouldn't be held hostage to a large foreign corp (Visa, MC) for CC payments.

But most countries didn't have that capability. Kudos to Brazil for putting something together for domestic digital payments so as not to rely on a foreign company.
