Google to expand misinformation ‘prebunking’ in Europe

good in theory but how will the topics used to illustrate the techniques be selected? I'm guess that CIA's Operation Mockingbird isn't going to be used any time soon, or ever

This is preferable to banning information. The requirements would be that it teaches techniques to detect propaganda, not to use any case studies that aren't really disinformation and just a different perspective.

If large tech companies use this instead of listening to government about which topics are promoted or removed, I would support this approach.

As another comment already said, propaganda operations would be a good starting point as this is the most important and most dangerous form of disinformation. Creating rumors of widespread disinformation could be a form of propaganda too. This needs to be included as well.
