Why offer that much throughput then complain when people actually make good use of it.
If you want people to buy business lines, make it competitive with your home accounts.
perhaps you didn't read the summary. He has a 300Mbps/65Mbps plan (300 megabit/65megabit = 37.5 megabyte/8 megabyte). He used 77 terabytes in a month. Most people only has 1 to 4 terabyte hard drives in their home computers. He used 77 terabytes. That would fill the entire hard drive of the average home computer about 50 times, and he did that in a month. Excessive much? Yes.
According to Math, 37.5 megabytes a second is 3.2 terabytes a day, so he had to be running full bandwidth for 24 days straight. Pretty sure all of our ISPs would be calling us if they noticed we were downloading at full speed for 24 days straight.
