Mario talked about the Earendil transition in his blog post here: https://mariozechner.at/posts/2026-04-08-ive-sold-out/

Him and Armin especially, have been involved in OSS for years and have worked hard to build communities around projects they’ve built and maintained. We’ve all seen enough projects become what you’re afraid of, Mario included. I’m optimistic that they’ll keep true to their goal of keeping pi open while building their other products around it. I think they understand the community dynamics necessary to keep a project like pi going. And they want it to succeed that way.
