Yeah he seems like a very thoughtful person and was recently having some sort of an existential crisis, questioning his atheistic world view and such. He made some blog posts about it, that he seems to have taken down since then (https://listed.to/@mo). I’d also speculate that he wanted a fresh start, and perhaps this was the plan all along. I hope he’ll find what he’s looking for!
This could also partially explain why SN got basically abandoned since the Proton acquirement.
