Matt's his brilliant vision and powerful team was offered to this community on a silver platter. He will simply do it elsewhere now.
Simple as that. Blockchain integration into the STEEM platform is that disposable and effortless. It's so worthless to integrate, apparently. Forgive me, but none of that adds up.
I wrote an API client that signs transaction. If I felt offended that people didn't respect me on the platform after writing it, I still wouldn't just walk away. I think my code speaks for itself, so I care less about proving myself with talk. I just let the code stand on its own. But that's just me.
I feel sorry for the developers who (apparently) put up the risk to integrate Matt's game, only to have it thrown away because he's so easily offended.
