Washington Post hack to post post-facto fact check

The Washington Post ran an article about the "inventor" of email, which it identified as V.A. Shiva Ayyadurai. But there's a problem! Ayyadurai didn't invent email. After publishing a risible "clarification" and some error-strewn sneering at critics by its ombudsman, amends are finally being made. But a correction remains to be made—because they're still fact-checking a headline they already accept is untrue.
