The way I see things is that having an Internet service that is in high demand is simply incentive for ISPs to peer with you.
Netflix reportedly said (link below) that it regretted offering 'unmetered data' to Australian ISPs, because they feared it would have a chilling effect on the availability of other streaming services.
Their fears were unfounded: Stan & Presto are both available unmetered on certain ISPs. (Quickflix went out of business, but not because of ISP deals, but because they couldn't compete in library size and other major ways -- I suspect there's simply not room for three Australia-based streaming services to license enough content to keep themselves afloat.)
