Yep, you are totally right,
Facebook has seen some backlash with its anti Fake news campaign.And if these 2 platforms keep on bleeding users left and right, they will have to restrict the access to Steemit and other blockchain sites, mentioning piracy on any other excuse(ponzy), and users will have to comply with new community guidelines. The only difference is that I believe we are a little bit more protected on the blockchain and free but maybe I am just deluded :)
