I don't buy the hypocrisy. Net neutrality requires ISP infrastructure companies to not artificially restrict end-users choice for legal content. Especially as ISP companies become coupled with content companies (Comcast/NBC Universal) and generate anti-trust concerns regarding throttling their competitors in the content vertical.

An end-user running an ad-blocker has literally nothing to do with the appropriate role of the infrastructure provider (which many argue should be an unbiased plumbing system).

I do think there are some ethical concerns for running an ad-blocker, but I don't think this is one of them.
