I am but a single datapoint, but the $100/month for home internet hits quite close to home. I currently pay $130 for Spectrum's gigabit cable internet plan. Their website offers it for $70, but that's only for the first year; they have raised that price by, apparently, $20 per year I've been a customer. We do not have fiber and my only other ISP option is a DSL provider that maxes out at 40mbps for $30. So sure, I can save about 75% on my internet bill by opting for internet that is 4% of the speed that I currently pay for. And this is in a rapidly growing suburb. I think $100/month is easily the case for places like my home, where local broadband monopolies still exist mostly unchallenged.
