Not here. It's a natural monopoly, just like sewer lines or electric transmission.
Where I live now, I paid $50k to get a private fiber optics line just not to deal with Comcast anymore. There were no other options. We _might_ get AT&T fiber, eventually.
Municipalities normally grant local cable monopolies.
But today there are other options. Starlink, for one.
It has not been a monopoly here for the last 2 decades (at least). There also was Wave Broadband nearby they serve some high-rise buildings, I got a private business-class line from them.
But it was not profitable for them to expand normally. They can't offer drastically cheaper service than Comcast, the installation costs in cities are huge. I also have Starlink as a backup, and it's even slower than Comcast.
So yeah, government actually works better than commercial companies for most infrastructural needs. And in particular, municipal broadband is usually head-and-shoulders better than anything from large commercial companies. It has higher consumer satisfaction ratings and is cheaper on average.
