Facebook, Twitter and all that crap are private sites. Of course they sensor everything that harms their image (although they somehow refuse to remove most ISIS accounts to this day). All you can do is publish your own content without relying on any other platforms, kinda how political activists published their literature even in the gulags. Steemit is great for now, we don't know what will happen in the future. Either way, I've seen a lot more former or even current government/law enforcement insiders speaking out against it, mostly on LinkedIn (go figure) and their own sites.
