American cable operators set up a separately managed and isolated SSID and DOCSIS service flow to provide Hotspot2.0 access for their cellular subscribers (among other things). XfinityMobile/SpectrumMobile SSIDs are everywhere now out of the box being hosted off of ISP-issued hardware.
That’s where we have to circle back to the parent comment - a smart TV operator could 100% go buddy-buddy up with Xfinity/Spectrum/Cox/et al. and get Hotspot2.0 certs at the factory level to go hop onto whatever cable operators they want to target.
Xfinity cable modem / router combos will create public Xfinity networks by default for many years now. Absolutely is something Xfinity could be selling access to for other corporations.
