There's a lot more "ifs" in hiring blocktrades than not. It's only a promise and no guarantees. Coding software doesn't always go as planned. I see it like this either

1. Pay up to 2.5 million steem for a hope

2. dramatically reduce costs and let the businesses innovate for themselves and focus on what steemit inc does best

I go for option 2. I would never want to put the success of steemit inc or steem itself into the hands of one 3rd party. talk about centralization.
