None of the other comments explain why misinformation makes money.

It's because stuff like misinformation, lies by omission, and rage bait all tend to incite very emotional responses in people. These people then engage with the post via likes, retweets, viewership, dislikes etc. that tell the algorithm to increase said post's reach to more people. Platforms want to consume as much of people's time as possible for monetization purposes, so misinformation really helps them.

That being said, all of this is pure speculation. If I were to guess why they disbanded their T&S team strictly from the headline, it would be because of incompetence.
