going down a legal road is not what I nor most people want to do. I have issued DMCAs before, as my content has been stolen and my courses sold on download sites. However this is a little different in that I published directly to steem my self. Also, to give steemit inc the benefit of the doubt here, I don't think this was malicious, most people dont have their own sites that are posting to steem.
