There's something to this. The things people hate about Facebook aren't caused by some user sitting down and typing a post, and in fact that kind of content gets buried in the feed anyway. The problems start with "sharing the story at the top of the feed" and "your friend liked X article which is really an ad". It's a more aggressive version of 90s email chain-letters.

Absolutely. I don't think most of these people woke up one day and suddenly decided "hey let's storm the Capitol".

Instead, these people were groomed over a period of months or years by way of recommending conspiratorial or outrageous content and it finally blew up.

So not only did Facebook create the problem in the first place, they also had plenty of early warnings about what's been going on, but it's hard to consider an increase in "engagement" (thus revenue) as a "warning" and even harder to act upon it.

This also raises another question regarding the efficiency of our intelligence services if large-scale domestic terrorism was organized all in public on a platform they had privileged access to.
