Only a subset of Threads users are currently exposed to the Fediverse, and I believe only partially (not sure if replies have been enabled yet, and if they are, if they're visible as regular replies, or under a separate heading?).
I'd also note that social media use differs hugely per country. See, for example, WhatsApp vs iMessage use in the US and outside, or how Brazil used to be big on Orkut. I wouldn't draw too many conclusions from Brazilian usage patterns vs the rest of the world.
