I don't even know (or care) who they are but I'd be willing to bet a lot of money on that being an uncharitable characterization of what happened.

I'm not sure about the best way of handling it. The tweet was unprofessional, but it did explain what was going on and had a visual aid in the picture.

If someone wrote an article debunking it, posting the link to that article would've been more professional. But I doubt something like that would be enough to justify an article.
