Yep, fuck Comcast. I'm waiting for some other options in my area. Seems like the competition has been promising unlimited gig-speed fiber in my area for years now, but so far nothing.
I pay extra for unlimited gig-speed w/Comcast. And of course if I didn't rent their router I'd have to pay even more on top of that, which frustrates me even more because I'd much rather get my own gear to save money in the long run. I won't knock them for taking money where they can get it (with the arbitrary data cap), but like others said, there really isn't any other competition in my area. On top of that, Comcast donated something like $100M to #BLM this summer, so it's not like they are hurting for money.
Believe you me, as soon as I have a viable option I'm jumping ship from Comcast.
