Ultimate data cap now cut to 1 TB?

Cox, you have a monopoly on broadband in my area.  I pay for your top package (Ultimate) for over a year and a half and now you want to charge me more for data usage.  When I signed up it was 2 TB and now you reduce it to 1 TB.  I moved here from Seattle where I had Gigabit for less that included unlimited data.  My career is in technology and fully understand how you are exploiting your customers.  Data usage has nothing to do with actual costs.

There must be a remedy to your exploitation.
