- "being hostile for ideological reasons" becomes entirely warranted when you consider the many CIA regime-change operations in the past.
- "Undermining the relation" (with the US) is just being smart about how much dependency one has on external factors, like exchange rates and infrastructure.
- The "investigations" are political posturing. PIX is not "unfair business practice", its a modern, cheap, state-of-the-art payments system that is better than what private businesses like MasterCard and Visa are willing to offer. I can think of plenty of ways they could offer actual value to customers so they can still be relevant. The fact that they don't, and chose to try and lobby against it tells me that its a lot cheaper to just buy some politicians and manufacture some controversy instead.
