Yes. Pretty much.

Pretty much all of Bolsonaro's allies have issued statements accepting the results. This statement by Flavio is more ambiguous, but given that most people from both sides have accepted the results, I still interpret it as a statement meaning "thanks, we tried, let's move on".

I could be wrong, but all signs are pointing to the results being accepted.

There's a chance these truck protests can grow and then a lot of the politicians go back on their statements. But I think that is unlikely at this time.

I completely agree. A more clear concession is still needed. Specially since there have been some truck drivers protesting on/blocking highways along the country waiting to hear what Jair Bolsonaro has to say about the results.

But the first member of the family to speak out making this statement (which to me still sound like a concession from his part) is a better sign than if he had been silent or made a statement outright contesting the result.

Maybe it's lost in translation, but the message in Portuguese has the tone of concession. The "Let's raise our heads" part usually means you have been defeated here in Brazil. So with that context, while I agree it is still ambiguous, it is still interpreted by us as a concession.

Yes. Here is the tweet. He is also a senator and campaign manager for Jair Bolsonaro.

One of his sons just conceded on Twitter. That's a good sign.
