Correcting the blatant misinformation about the topic:

- PIX project started in 2016, public launch in 2020

- It was not "launched" by any President; the Brazilian Central Bank is an independent authority, with it own mandate, not a branch of the executive power

- PIX was co-developed with institutions of the financial sector

- It's a protocol that participants must implement, not an app. The specification is even on GitHub. I don't know what you mean by "its code is nowhere to be found".

- The Brazilian Central Bank is acknowledged as a benchmark, rather than "proverbially incompetent public work force"

Your arguments are pretty lame. Pix was indeed launched in the Bolsonaro administration, but it is incidental. You are flailing around the bulk of my argument, which is about the source code openness, without actually attacking it.

It might as well be illegal today.

So, lets open up its code!

You should read up on "autarquia federal". The Central Bank is not part of the government.
