He did have a problem with the machines for a long time, and so did other candidates and parties. It was them who changed their stance to avoid being on the same side as Bolsonaro.
I don't agree with that. I'm curious about where a person can verify that their vote is actually the one counted? Because you can't in the US (whether by mail or in person).
Don't get me wrong, I think and individual printout would be great! And even better if you could go online (or somewhere) and verify that the vote counted was the one that you have a receipt for. I just don't think these improvements justify Bolsonaro's claims.
