Let's be honest here, many people who tether do it to give other people internet access.
As for the buffet analogy, the buffet DOES sell you an "unlimited" buffet, but you can't take it home and eat it... You paid for unlimited food, what does it matter if you eat it at home...
I'll say it again for clarity. If you don't agree with the TOS, dont sign it. Lol, I love the idea of litigation... "Let's sue them for stopping us from stealing".. why didn't Napster think of that defense.
Because when you take food home, you are obviously taking more than you could eat at that one sitting.
But being that we have caps on our "unlimited" data, we are not getting more than we paid for. We are simply getting what we paid for via a different device. I am taking my food and eating it with different utensils rather than eating everything with a fork.
That's the difference.
Now if I eat more than my share of data, charge me, just as many buffets will let you take some food home, but they weigh it and charge you extra, because you are going over the limit.
You taking the internet service off your phone and giving it to another device is akin to me taking the plate from the buffet and eating it at McDonald's. I mean, why should they care, its still the same amount of food........
The reason they care has already been explained at length. Because YOU signed a contract.
Think about it this way, you've got a gasoline pump with unlimited gasoline. (Bandwidth)
But you can only pump thru a straw. (Your phone)
The very reason the gas (bandwidth) is free, is because there is such a small amount being drawn out at once.
Now, switch the straw (phone) with a garden hose (computer).. they are both drawing from the same "unlimited" gas pump, but at vastly different rates...
There is only so much content you would want to use your phone to access, that's what the carriers are banking on. Once you start using your computer the whole internet opens up.
Jeebus, American Morals have gone up in smoke.
Your new analogy is exactly why they should be clamping down on Bandwidth, not which "hose" is being used. I, for instance, would still use that straw to send work emails and be available on Office Communicator during my train commute. Who they should be targeting are those users who take that garden hose and use it at home to stream Netflix or spread it around to friends in the area.
