The problem is no one has really made an effort to take over in the news/politics space. Meta basically decided Threads wouldn’t be for that. Mastodon exists, but given it’s nerd-based nature it’s way more tech focused. Then there’s Substack’s half-assed effort, but they seem happy to focus on newsletter subscriptions for now. So there’s competitors in microblogging generally, but there’s still zero competition in news/politics.
