The additional problem to this is that they guided the industry and their own platforms to actively generate that much content. No effort was made to naturally or organically slow the creation or even perform any sort of de-duplication. So whatever argument they use for "we're too big, their is just too much content" is directly on them.

Social media is a slot-machine essentially, and in order to do that they had to mobilize and incentivize entire industries to revolve around generating millenias-worth of content.
