Yeah, they definitely must have considered SMTs to some degree and maybe they just don't have a full understanding of where SMTs could/would fit in with their ecosystem. I think it is short-sighted though, personally. I hope they release a public statement, but I imagine it came down to fast money, trying to get a footing in a blockchain 'at the ground floor' and trying to use their influence to increase that blockchain's value. Power to them, but I predict it will hurt them in the long run. That said, to a degree I'm biased, being a committed Steemian.
