Precisely. These "things" don't come out of the air. They have a history and there is a reason why they behave like they do. Trying to argue that the internet should be like the [insert old behaviour here: cable tv, telephone, etc...] is ignoring the story as a whole and trying to push the argument for the wrong reasons.

How is the type of switching relevant, exactly?

Why do you think the telephone had different prices according to the distance you wanted to phone ? That is because a dedicated circuit had to be established for your call to be made (sometimes with multiple protocols in between). This was crucial and defined the way operators organized and made their businesses. Unfortunately these businesses did not evolve as much as tech did and now you have net neutrality being questioned by the FCC chairman without a hint that he understands why do these companies behave like they do.

Now, my turn:

why do you use an app to call/talk to your friends instead of calling their number on your smartphone, exactly ?

Uh, I don't, and I don't understand why you're asking me that.
