From a US perspective, for your #1, the idea of people “shopping” for broadband, is astonishing. Most people here have available to them one single DOCSIS provider and that’s it. A few lucky ones have a FTTP option too, but that definitely not available to more than 25% of addresses.
(It’s true that you can use cellular for your home internet, but I consider that extremely compromised.)
Starlink shattered this monopoly in my area.
