Nice try, but your analogy isn't appropriate. It's Apples v. Oranges. There's a price difference between business-to-business sales and business-to-consumers sales in everything. Someone paying for 250gb a month for residential use and a business paying for 1,000 gb a month is based on estimated usage. What telecoms are doing, essentially, is charging the business for 1,000gb and then dictating through fee what they can do with that 1,000 gb. The 1,000 gb is already paid for. How you use it shouldn't be up to the provider.
Bandwidth is a public utility provided by for-profit corporations and if it's going to be metered, fine, but don't tell me that I can't hook up another lightbulb and still use the same amount of electricity.
