Fact Check
The claim is well supported by the fetched PANews article, which specifically says Josh Stark is leaving the Ethereum Foundation at the end of the month after five years and that he worked on communications and coordination for major Ethereum upgrades including The Merge. PANews also provides the original-source link to Josh Stark’s X post (https://x.com/0xstark/status/2044757694389670239), which is strong provenance even though the post itself could not be fetched in this run. Independent corroboration appears in search results for The Block article 'Ethereum Foundation exec Josh Stark is stepping down - The Block,' dated April 16, 2026. The only notable limitation is that direct fetching of The Block and X failed, so confidence is medium rather than high.
