Facebook has a coronavirus problem. It's WhatsApp

I'm not sure I get how the problem is related to WhatsApp.

WhatsApp is a platform for (largely) private messaging among individuals or small groups. It's a SMS/Call replacement/enhancement. I wouldn't want health officials, or anyone else for that matter, to be monitoring what gets exchanged over WhatsApp to detect misinformation. This is not a platform problem, this is a "there's disinformation out there and individuals are spreading it problem", I think.

This is different in my mind from semi-public/public platforms a-la Facebook, Twitter, etc.

Goverments have a problem. People can exchange information without oversight.

This is frightening, to say the least.

Facebook has a Facebook (or Instagram) problem. Most misinformation originates from there before being spread further through private platforms such as WhatsApp.

However I am not sure if this is a real problem for them. After all, it keeps engagement levels high on the platform; if anything, idiots and crazies who crave misinformation are more likely to click on ads.
