I don't really know anything about Lula (I wouldn't have known this was Brazil if it wasn't explicitly mentioned, I only know from the Wikipedia page 30 seconds ago that their full name is Luiz Inácio Lula da Silva and "Lula" is a nickname), so I can't say if they're "fine" or "evil", but one does not simply get to disregard the implications of censorship (of anyone, let alone a political party) when it happens to be done by a private corporation.
Especially when it's a foreign private corporation that's already deeply suspicious for political interference in multiple nations, as Meta is.
