(My thoughts on this lie with SuperMicro/Apple/Amazon being correct - Bloomburg/Business Insider are bottom feeders and pretty much scrape any 'sensational' news they can without bothering to test veracity. After all, doing *actual* pre-publication fact-checking would mean someone else might publish it first and get all those ad-revenue-generating clicks!)
