Another feature that could spark more discussions: Instagram’s network isn’t starting from scratch. It will build on the company’s own network yes. But over time, Threads will also let you follow discussions on Mastodon and potentially other services that adopt ActivityPub. Tumblr and WordPress, which share a parent company, have both said they will support publishing on the protocol. In a year or two, then, you might read WordPress blog posts in Threads — or read Threads posts in your favorite Mastodon client. It’s an almost unthinkable reversal from Meta’s extremely lucrative walled-garden strategy, which it has employed for its entire history as a company. But Mosseri told me that decentralization is the future of social networks — even if it means that someday a disgruntled Threads user will be able to take the following they build in the app to another network, never to return.
“There definitely are trade offs,” Mosseri said. “You’re giving up some control. But there are benefits. I do think over time, it’s going to be a more compelling value proposition that other apps are going to offer. And I think that should attract more creative talent over the long run.”
