I personally do not think much will change, if anything... there is little practical downside to the choice of the FCC, and so much fear mongering from the other side of things that it greatly strains credulity.
In the next 1-2 years? Sure. There's no way they're going to go full corporate dictator at the outset. The first thing they'll do is start negotiating with the big content providers, while fending off the inevitable legal challenges. They'll also need to go full throttle on getting friendly Congresspeople (mostly Rs) reelected next year.
After that? I think we can expect to see a lot more zero rating packages and more investment in their own content services. Data caps will be pushed down to make these services and zero rating more attractive. Further down the line, they'll be extending their "partnerships" with more and more edge providers.
Eventually, they'll have enough deals that cover just enough of what people use that they can start throttling down anything else while most people will neither care nor notice. It may not happen in a year or two, but watch for *this* to happen. It won't at the outset.
You really think they've been pushing and spending this much because they *don't* expect to maximize their revenue and control?
