Bluesky is explicitly promoting their system as “choose your own censorship” kind of deal, which in the way it is framed could look very attractive to right-wingers looking for an alternative platform. While this is technically also true for the Fediverse, it isn’t promoted as such, and rather has a reputation for the opposite, as most fedi server admins are center-left leaning.
Bluesky might be also more left-leaning right now as obviously there is little reason for right-wingers elsewhere to switch away from Shitter to another (mostly) centralised platform, but given the overall low user numbers this could switch very quickly.
I guess we will have to see how this develops over time and get some answers from Brazilians that have a deeper understanding of the current social dynamics there.
Due to the language divide it might end up as two distinct social spheres, like Fedi’s Japanese bubble, but that’s a best case scenario for Bluesky I guess.
