Optimum had their entire service area bought out by Comcast the day after I switched. Comcast has since broken every major utility at least twice and my fiber connection three times by working on the old infrastructure. I think Optimum won that trade. I can't imagine many residents are going to prefer Comcast over $80/m for no-bullshit internet, especially after the water main break they caused last week.
These FTTP providers have the game solved in Texas. I've seen them do 500-1000 homes in <30 days. Their directional drilling expertise and aggressive neglect for 811 seem to get things done very quickly. There are some areas with competing fiber providers now. I've got 5gbps symmetric for $110/m and I live in the woods. Trees go through power lines and the fiber infra is completely unaffected. The only utility left to bury is the electricity, and they're actively working on that in some areas now.
