I get that this plan may work for you, but I am confident they have an ulterior motive which you will be forced to contend with in time. For me, personally, I am not a fan of turmoil and having to make concerted efforts to constantly get what I expect and deserve. So, when I finally lost all desire to keep dealing with the local cable company every 6 to 9 months when they'd try to screw me over, I fired them and will never, ever go back. The cable industry has survived on what I consider unethical or very marginally semi-ethical practices, and as such I no longer trust them at all.
Hell, when TWC sold the local service to Charter and rebrand as Spectrum, they just cancelled my plan without any prior notification and they moved me to an equivalent priced plan which was 25% of the speed with data caps. I raised hell and they didn't care. Now they are offering double the speed (still half my prior speeds with TWC) at the same price if I were sign up as a new customer today and they are bragging their plan is cheaper - though it isn't. They refused to honor my prior plan and then attempted to argue that if I would get their cable TV service in addition, it would cost the same, thus saving me money. I call BS on that. I don't want to support the industry any longer as they are losing and getting desperate and not helping customers at all. To me, your "free" plan in part of a larger scheme to screw you over.
I have no real skin in the game. If they screw me, I'll just drop it and buy that antenna.
