I am a current @shadowbot member and I have been very impressed with the composure and quick responses Mark was able to make to the questions by congress. He made it very clear that Facebook does not sell your data but sells advertising that can target based on the data they collect. He explained and informed many congressman that did not understand how all the information is given freely by the users from Opt in and Opt out features. I think the amount of censorship concerns and ideas that it breaks the 1st amendment right to free speech are great for Steemit because the self governing user platform here allows for free speech and content deemed unfit by the users not the site is what gets hidden.
