Expecting a content provider to invest in net infrastructure is unreasonable. The costs are too prohibitive,not to mention duplication
No one is expecting them to invest in anything. That's a big misconception. Just don't impose control on bandwidth or the "common carrier". There are multiple carriers and there is nothing "common" about them except the political. Do you use YouTube? You find they have a "Standard User License" - which is a feature-free default option for the hoi polloi. Some extra bucks reveal a bunch of fancy APIs - including analytics on the viewers complete with their spend histories & projections. The premium, gold and platinum licenses avail you of all kinds of magical options. Additionally, Google censures, warns, suspends, bans and otherwise arbitrarily restricts the accounts of users for various reasons. Now, this is just business and no one has to use the globally dominant YouTube to advertise products or reach the market. Amazingly, Google does a complete somersault and insists ISPs should not have the freedom to manage their own products. Apparently carriers are "common" - although none of them dominate the bandwidth market as much as Google does content. It seems the "Net" is only made of carriers - handsets and devices don't matter - and the content is an insignificant top layer. Hah!
You can substitute Google with Facebook, Twitter, Microsoft, Netflix, Apple and other prominent members of the neutrality choir.

None. Price control of proprietary products is a no-no.
