I theorize that FB paid the leaders of Steemit for secret information and data during the great hardfork of 2018. FB took the info to help work out the bugs of their new Libra coin. If you take note of the corresponding dates and immediate toilet flush of Steemit you will realize what I am trying to communicate. I agree with this poster in that its all about the money. Libra will happen and Steemit will be a memory along with other trailblazing coins who sold their souls to the devil.
