I’m not confused about either, but you are certainly trying to confuse the issue. Peering connections are typically 10 or 100Gbps, which is astronomical bandwidth, and most streaming services use local presence and caching to reduce backhaul and latency and improve customer experience. And between the major ISPs peering is generally mutually beneficial so there’s minimal exchange of payment.

I’m also not a lawyer, but consult one in antitrust about the particulars of an entity with a monopoly using that market power to undercut competitors who need their monopoly service to provide their own, e.g. Microsoft bundling IE with Windows when it powered 97% of PC desktops.

“Most of America is shifting from wired networks to wireless?” For phone service, sure. As the PRIMARY broadband internet connection? Hardly: https://technology.ihs.com/468148/broadband-internet-penetration-deepens-in-us-cable-is-king Pew’s last report said more than half of America had connected to the Internet via wireless but did not say it was the primary or only way.

I have and love T-Mobile, and even in NYC, with LTE service nearly everywhere, it’s not reliable enough to be my primary home service. Why do you think TMo offers a high speed router for free? Because it’s cheaper than expanding network capacity. They are offering TV without a cap because on phones, the small screens means the content can be much more compressed and not crush the network. As for your general statement, I’d hardly call four carriers, where two are owned by two of the largest broadband incumbents, plenty of choice.
