It's not fixing facebook. No one was saying "fix facebook" when Barack Obama was praised for using it and it was part of his strategy to win. For example:

The "facebook is bad" started happening when Trump won, imo. Essentially the establishment on both sides realized that it could also be used against them as much as for them. It feels similar to AM radio, which conservatives successfully used and you started to see cries for the Fairness Doctrine to be reinstated.

I agree with the post that this wont solve anything.
