As the story goes, it seems as if the company is pulling back on upload and download speeds (from 10Mbps to around 0.25Mbps) for users who have consumed between 7GB and 10GB in a month, which is comically low even compared to Comcast's hated 250GB / month usage cap

In other words, use your connection as a normal person might, and you're done. There's a complete disconnect between how ISPs think you ought to use your connection, and how people are actually using them.
