Such a naive take. Like the US government espionage is not deeply embedded in even the most basic infrastructure, let alone payment gateways. They probably spend millions on huge data pipelines straight to the fucking pentagon.

Nothing naive about it. Brazil is not USA. It hasn't exactly demonstrated an ability to "deeply embed" itself into internet backbones the way the USA does. The problem with Pix is: they don't need to.

Lack of capabilities limit the scope of government tyranny. It used to be that the government didn't have the manpower required to audit everyone and everything, so only the transactions above some threshold would be monitored. With pix, they are monitoring 100% of transactions now. This is a massive gain in capability that should not be ignored.
