I am not stating he is somebody Obama would have chosen to lead the FCC, but Obama saw fit to appoint him. A democratic majority senate saw fit to approve him.
I do not necessarily agree with Pai, but actually take the time to read what he says instead of snippets taken out of context and it's hardly nonsensical or untruthful. In going through this process of trying to actually discover his views, I found several interviews [1][2][3] that I found informative. His major view is that you regulate as necessary. Let people compete openly and freely with as few rules as possible. When bad behavior emerges deal with it as necessary. He is focused primarily on competition and simplifying what is required for ISPs to get in and operate. Adding hundreds of pages of rules and regulations does not really fit into the picture here.
I don't necessarily agree with him, but he certainly has a perfectly cogent argument. And I think disagreeing on the right path forward is perfectly fine. A number of small ISPs have written to Pai expressing support of his plans to dismantle the rules. Others have written him expressing disagreement with those plans. This is all a far cry from calling somebody a nonsensical shill, a liar, and so on. And in the vitriol on both sides, I find most have very little understanding of what it is they're even getting so riled up about.

Out of curiosity, if you would humor me. Why do you think Google Fiber failed to achieve significant sign ups in the region it setup in? In the ~6 years of operation to 2016 it managed an estimated 0.07million television subscribers, 0.45 million broadband subscribers. They've since rolled back further plans for expansion and engaged in lay offs in downsizing. Imagine the doomsday scenarios come true and suddenly ISPs are demanding $10 for social media, $10 for gaming, ... . What effect, if any, do you think this would have on the outcome?
