This might be the answer to you second question. No one seems to have taken the Bloomberg story to be true. Just went "that's dumb" and dropped it. In fact the only times I've ever seen it resurface is in a context to point out something negative about Bloomberg (like now), not the companies named in the article.
Sort of like the Elon Musk defamation case that just ended. Plaintiff didn't get anything because people didn't turn on him due to the accusation, they turned on Elon.
If it's not believed then you couldn't have suffered harm.
