No, I'd suggest reading the next line of my comment. It "at least cites some actual stats" rather than quoting Cardi B and the admins of a Timothy Chalamet fan page.
That's an intentionally silly reading of the WaPo article's title, contents, and implications. They're fairly obviously not making the claim that zero Brazilians care. They're making the supported claim that Twitter's seen a decline in Brazil in recent years and is probably going to just shift over to other platforms, as we've already seen to some extent.
3% of Brazilian population is still 6.45 million people who primarily use X for news. There are 23 million X users in Brazil. That's a lot of people.
