I didn't read the ruling, and I'm not sure if any one of those points is a "killer" vs the others, but I have seen that autonomy is a big check to determine contractor vs employee (touched on by 2, 5, and 6). Loosely speaking, when using a contractor, you're really only supposed to specify the end result/requirements that you want, and then it's up to the contractor to figure out how to get there, be it a new room expansion, or a website. With the constraints of 2, 5, and 6, it seems the court feels that drivers don't have that much autonomy.
