There is one little thing wrong with your argument. The cost to the carrier does not depend on how much data you use. The marginal cost of an additional megabyte is in most cases zero. The reason is that at the top level the large telcos are not paying for usage as much as they are paying for capacity. At some point when the capacity is reached but the user wants more bits and wants them now, the marginal cost becomes millions of dollars - upgrading large scale infrastructure is not cheap. So while individual user's data usage is related to the total costs to the operator, the relation is far from straight forward and is very indirect.
In short, they are not charging anyone based on their actual costs - they are just trying to come up with highest prices they can get away with. The data caps and tethering restrictions are just smoke and mirrors to try to convince some people to pay more than others for essentially the same thing.
However you justify it is on you. But make no mistake, the act is stealing.
... Suddenly they are delivering 20% or 100% more data at the same price. ...
If you have limited data then its a little unethical
What was stolen? What are they out? If you say money that I would have spent on a tethering plan, you're wrong. I wouldn't spend one extra cent on a tethering plan.
It's not like AT&T sat down with me and we came to a contract with mutually agreed upon terms. They basically force their terms down our throats because they can, and we just have to accept it.
It's not illegal, it's a violation of your contract with your service provider.
They catch you, they bill you for services you have not been paying for, or they cancel your service.
It's that simple.
Don't like their contract terms? Don't do business with them.
AT&T didn't force anything on you. You knew the terms and you agreed to them. If you don't like the terms don't give them your business. Simple as that.
I agree with this.If you have an unlimited plan you should be paying for tethering. Unlimited data is based on the data being used on the phone, not another device. If you are on a tiered plan no, your paying for the data use it how you want.
And go where? Every big company uses 1-sided terms. AT&T won't even let me cancel my data plan and use my iPhone WiFi-only.
As for not forcing me, it's not a good argument anymore. This day in age people need cell phones. When gas becomes too expensive, you're argument would be "well don't drive". That's not really feasible.
However you justify it is on you. But make no mistake, the act is stealing.
Tethering's included in Verizon's share plans.And go where?
If you have an unlimited plan you should be paying for tethering. Unlimited data is based on the data being used on the phone, not another device. If you are on a tiered plan no, your paying for the data use it how you want.
the data (internet) is still generating from that phone. Its not like you are putting that sim in another device.
True. But when they offered unlimited plans they based it on the phone using the data. Not tethering to a PC where you can hit it with torrents and other high data uses that a phone isn't capable of.
Not immoral. Although illegal for sure (contract violation).
It all depends on the contract. It's not a good thing to break an agreement. Didn't we learn this in kindergarden?
Looks like the FCC agrees. Verizon can no longer force you to pay $20/month to tether: http://www.gizmodo.com/5930610/verizon-officially-cant-force-you-to-pay-20-for-tethering-anymore
So, now that it is not illegal, and hence immoral, is there a tethering app available without jailbreaking my phone?
