I'd encourage people to read the article, because it's pretty no-nonsense and has some other interesting details and background information. It's not very long, either!

But here's the important part that the headline speaks of:

Decentralized social network organization Mastodon said Monday that it is planning to create a new non-profit organization in Europe and hand over ownership of entities responsible for key Mastodon ecosystem and platform components. This means one person won’t have control over the entire project. The organization is trying to differentiate itself from social networks controlled by CEOs like Elon Musk and Mark Zuckerberg.

While exact details are yet to be finalized, this means that Mastodon’s current CEO and creator, Eugen Rochko, will hand over management bits of the organization to the new entity and focus on the product strategy.
