The reason this move isn't popular is because it seemed like local docker development (for any size corporation) was always going to be free. If I personally had known this was in the cards I would have invested (time, money and effort) into alternatives earlier on. Instead they killed all the competition and are now demanding money. So yeah, this is the first move by Docker that has made me kind of mad at the company.

How does this affect consultants that want to introduce docker to large corporations but small teams? A lot of scenarios become crappy now.
