I think most of us already deduced as much. Securities must have some sort of centralized issuance and redemption -- otherwise they can't attest to right of ownership in anything. I'd rather they opine on some ICO tokens or more centralized cryptocurrencies. This doesn't tell us anything new.
This is a weighted decision which I can respect. Bitcoin isn't 100% secure indeed, so there's no need to lie to people
That's not what they mean by
security. They're referring to this definition:
a certificate attesting credit, the ownership of stocks or bonds, or the right to ownership connected with tradable derivatives
Bitcoin is still the most secure payment system in the world. Nothing new there, either.
