Thanks for the input on the salt, I'll try it again and see what I am missing on the cavey sensation.

You have a good point with electric sources being a differentiator. This is like with watered bottles saying their water comes from a natural spring in a mountain.

Here's another viewpoint to that, if you will: maybe you are paying a mark up for the source (or the assurance of such source, depending on the marketing) and the pure commodity itself doesn't have to be marked up for it.

As for internet, I think quality happens because businesses tier it to be. And, of course, with pure internet you have to pay for what amount you have used. I still don't think you need to go full bells and whistles as it is more reasonable to just pay what you used. I understand though that some areas don't have much choice on this.
