With respect to VC funding route vs. ICO. I see many reasons why they utilized a VC. First, Comcast is a multi-billion dollar publicly traded US based company thus financial resources are not an issue, especial he small raise. Second, as you are likely aware, there is the risk associated with an ICO, which is relatively a new mechanism and under heavy scrutiny globally with no defined parameters from a regulatory standpoint (recent SEC subpoenas have been served to ETH based ICOs in the US), a public company like Comcast has little benefit and material risk in using an ICO.
