The article uses the example of Covid misinformation spreading virally on WA, and while it's true that the information being spread is false (in the examples that they give), it's appalling that their first instinct is to bewail the fact that people's private communications cannot be surveilled and suppressed. This article literally and unironically contains the sentence: "But what makes WhatsApp potentially more dangerous than public social media are the higher levels of trust and honesty that are often present in private groups."
Yes, trust and honesty. That is what's wrong with WhatsApp.
