If we get two chains people will follow the money. People doing that already with tags, links, and so on. They will post on both chains. We all own different tokens and coins beside steem. It's nothing wrong with this. Most of us don't care about decentralization. My cat's photo doesn't need to be forever on the blockchain.
And if Sunny boy destroys the project people will move to the next one. Like Dan with Voice. Would you like your photo for the avatar? Not me.
And please don't get me wrong. I care about steem otherwise I wouldn't be here for four years every single fucking day for hours and hours.
But I'm not blind either.
