Yeah, for now I'm skeptical because they're Meta and they have to find ways to monetize this service, but on one day they've already overshadowed the rest of the fediverse easily. Even if they can't profit as effectively off other instances, their instance is already ridiculously big and profitable regardless; the scraping thing really sounds like fear mongering. So if the only downside of federating with Threads is that my federated timeline would get cluttered with business accounts posting ads, I'd be alright with it, as long as I can get more content on my Home timeline from LOTS of people I want to follow who are not willing to interface with Mastodon, Pleroma, etc. Unless they force regular user accounts to publish advertisements to people outside the Threads instance, I'll take it
