Mistakes will happen, the team will learn from them, and their product will improve.
Even if it set out to achieve its original goals flawlessly, it fails to actually solve the problem Google faces in the first place (being a platform for misinformation). If you got all the way to a conspiracy theory video, is Encyclopedia Britannica really going to change your mind? And being a not-flawless computer system, it will _always_ have false positives, which means as long as it exists it will flag events like this as misinformation. The latter, in my opinion, is inexcusable. Any engineer building any sort of classification system knows that there will be false positives, and nobody at Google thought that this would be problematic and stopped the system from being built.
The team that built this should be dissolved. This was a bad call on the engineering side, the product side, and the management side. Nothing about this was a success.
