Yea this has been an issue for a while and who I vote for president IMO should have a strong net neutrality mind set.
Personally, I see it really hard for a ISP to limit the last mile of their network to your house, esp since this means an ISP can push priority on their services over various other internet services (similar to how Microsoft pushed their software in their OS over allowing other searches, media players, browsers, etc to be used).
I do however see ISPs starting to block and restrict the bandwidth file sharing protocols might use.
