Oh please, I've used Cox before, and they were pretty decent for an ISP. They upgraded their systems at one point, rendering my cable modem unusable, so they sent me a new Surfboard for free. Their prices were good (compared to other ISPs I've had since I had to move away from there), and the prices were stable.
The company that really, really sucks is Comcast.
I've never heard of Cox continuing to charge people after they canceled their account (Comcast is famous for this), or for making it almost impossible to do (again, Comcast is famous for this; I think I was on hold for 2 hours doing this when I had to move out of a Comcast service area).
Cox also lets you just buy a cable modem and install it yourself, without a visit from a technician. Comcast and other companies require you to have a tech visit and charge you $100 just to plug in a modem.
I also don't remember Cox having any kind of 3-strikes system like Comcast has.
I see exactly what's going on here: Cox is the best of all the cable ISPs, so they're being run out of business so Comcast can buy them up for pennies on the dollar.
