A sizable coalition of technology companies has today taken a stand in favor of net neutrality in the form of a letter to the Federal Communications Commission. The group, led by giants including Amazon, eBay, Facebook, Google, Microsoft, Netflix, Twitter, and Yahoo, challenges a proposal the FCC is considering that threatens net neutrality.
Privacy is a different matter than network neutrality. Destroying privacy is the business model of most of these companies. They operate a service nominally for free, but you pay with your personal information which is sold to advertisers. In contrast most of these companies gain nothing from not having network neutrality, and some (Netflix especially) stand to lose a lot by losing it. It would make every major internet company have to pay kickbacks to ISPs or risk having a disadvantage in reaching their customers. There's a good business case against it from all of their perspectives I think, entirely apart from the political ideals held by people on the internet.
