Eugen Rochko is stepping down as CEO of Mastodon as the platform transitions to a non-profit structure. The move aims to ensure Mastodon's long-term sustainability. Rochko will remain involved as an advisor. The new leadership team includes Felix Hlatky as Executive Director, focusing on financial sustainability and stakeholder engagement. Mastodon raised funds to aid the transition and will focus on trust, safety, and technical infrastructure. Interoperability with other decentralized networks like Bluesky will be left to third-party projects. Mastodon aims to remain 'billionaire-proof' amidst competition from platforms controlled by wealthy individuals.
