The Steem blockchain is just code, and we're all generating it with every keystroke or click here on Steemit (and elsewhere). It's all open-source and free for all to use. It's free, high-value, data that has already been sorted and sifted through by intelligent human minds. OF COURSE there are nefarious people and groups analyzing and storing it for their own use. Surely you're aware that the government is fully corrupted and owned by elite people, many of them globalists who don't give a shit about countries, or you? I hope? So then you know there are people using the blockstream for evil as well as good. End of story.
