To me Facebook’s main issue is having a revenue model dependent on advertising boosted by engagement.

This is the main reason we end up with filtering bubbles, contents that needs to be consumed fast and push people to react, relying more and more on anger over most other emotions, with no need for veracity or depth, or bringing anything lasting to the user; the other side of the coin being the privacy debacles coming from monetizing that engagement.

I don’t see facebook doing any effort to mitigate these effects on their users. On the contrary we had many reports of research to increase engagement, direct the users emotions and test the different algorithmic strategies.
