Notably, Comcast does not have bandwidth caps in markets where FIOS or other high speed providers have coverage. These caps are purely a way to capitalize on a monopoly position.
I called Comcast to complain and try and avoid paying the ETF (it was at $180 because I signed a 2 year contract) with some kind of benefit: remove my data cap, drop my rate, something. They wouldn't budge an inch. Told me I was already getting a promotional price from them and that the data cap (which I'd already hit 2 out of their 3 grace overages) was non-negotiable.
Switched to the alternative provider, and I can't be happier. Looking forward to Comcast dropping their rates and/or data cap, but I'm hoping that I never have to be their customer ever again.
Comcast doesn't consider local(ish) providers as competition, this really only applies to Verizon etc.
