additionally, because comcast and DSL providers are using existing wiring in what are often very old buildings that are difficult to rewire (at the building level moreso than the unit level), that stuff is often just going through mazes of wiring with tons of interference and really inconsistently performs. fiber is honestly just easier to pull through three stories of 100yo walls than coax, afaict, and it doesn't care if it runs next to power or other data as long as you don't break it. i wasn't able to get full gigabit when i lived in sf with sonic, but my latency and general reliability was WAY higher than even with comcast business.
