Isn't "preferential caching" just Netflix providing a caching server for free to the ISP? Is this that different from Netflix building more CDN servers worldwide? It is Netflix paying in either case without exploiting their monopoly powers.

Clearly not a pro but I think it comes down to who Netflix is paying, or even helping out. Because they gave Nextlight a free caching server, any competitor who can't afford to do the same now has decreased performance.

That is an interesting way of looking at things. Netflix adding a cache has absolutely no impact on what any competitor does, or the quality of their service. It will function precisely the same the day before and the day after a Netflix cache is installed.

Actually at the very large ISP I worked at customers saw better performance because the back haul wasn’t congested with Netflix traffic.

Yes; this, broadly, is why I think "neutrality" is kind of a silly concept.
