While the existence of net neutrality-breaking ISPs could have caused any of these companies to fail in their infancy, their current position in the market allows them to largely benefit from this environment.
They may have added costs, but to them, that may be worth it if it artificially filters out possible future competition.
It seems to me that reaction to this has been tame so far. I believe EFF and phone calls alone aren't going to do anything. You basically need awareness on the level of blackouts.
They are some of the biggest companies in the world and they just seem to be rolling over at this. What gives?
