What makes you think a more expensive ISP will go against their interests and refuse to maximize their profits by selling access to information that they are legally allowed to share? Are there expensive "privacy"-branded ISPs I'm not aware of?

I don't live in the US, but here's a link from eff:

That doesn’t mean anything. It’s the same with Apple pretending to care about privacy right now while it is a competitive advantage.

You're lucky if you live in an area with more than one ISP. lol
