At one of my previous places, AT&T offered FTTN, but only if you used their router. The router somehow managed to break next-level NAT, so there was no way to use FTTN without giving AT&T access to your LAN. That violates California's network neutrality laws that prohibit discriminating against certain devices (though so does every single cell carrier plan that prohibits tethering, or swapping a phone with a tablet or a 5G dongle). The cell phone companies around here also all have some form of blurring video for some streaming providers, and bundling subscriptions to other video providers. Comcast definitely weaponized data caps with absurd overage fees, and also didn't invest in backend network infrastructure until they were under 3MBps average video streaming speeds on their 100MBps plans.
