Interesting post, we should read the service terms but most of us don't do it, some of that changes are to worry about, but I suppose that if they use some of those terms agresively this platform will definitely die.
This is open source so, copying code and changing some aspects, like the logo the name of Steemit and so, wouldn't be so difficult for the community.
I don't really think that the company could risk they relative success, for applying some of the as you said "mumbo jumbo" terms here exposed.
Congrats for the post.
