I agree. But source/destination isn't the only way that ISPs discriminate. They can also discriminate based on the type/protocol of content (when revealed). See the way they used traffic shaping with bittorrent, what was that 8 years ago now? That was communication between peers, potentially within the same ISP.

e2e encryption mitigates the impact ISPs can have when looking at the protocol/contents. But there is still work to be done to prevent them (without regulation) from having an impact based on source/destination without going the TOR (or similar) route.

Begging your pardon, but net neutrality isn't and has never been about traffic discrimination by type. That kind of traffic shaping is not only acceptable, it's desirable. Services with real-time requirements (VOIP, streaming, etc) can and should have priority over non-real-time services. I'm sick of people polluting the net neutrality debate with this misunderstanding and discussion on a site as knowledgeable as HN should be better. Net neutrality only covers discrimination based on source/destination and we need to push back against upset torrenters muddying the waters.
