I wonder that myself at times...then I remember I don't give a shit since I only use my cable company for internet...for now. Mostly because there has been nothing better.
Where I live, Cable is superior to AT&T's broadband. The only other option around here for the past 24 years...and well...FUCK AT&T.
Now that Starlink is becoming more widely available, I am going to switch as soon as I can.
Reviving a dead thread, but cable may make a comeback if the streaming services keep up their shenanigans. First they remove everything for their own in house programs, then they start the same "Packages" crap the cable companies do. If the price is gonna keep going up for less of what you want, you might as well go back to cable.
Many older folks are just use to it and can't be bothered to switch or try something new. Plus, now that PVR is as common as it is you can record what you want to watch and watch it when you want skipping the commercials.
