The OP and his brother are neighbours. They are family. As family they own (or rent, I don’t know) these two properties. To all intents and purposes the properties are held in common, as is the internet service (the OP said he would make a certain amount of recompense to his brother).
Why should he compensate his brother? His brother is not losing anything by letting him use the wifi. The only one that is losing is the ISP by having to provide for more services than they planned.
I would agree with you in cases where a neighbour piggy-backs without permission on an unsecured wifi connection for which they contribute nothing. But this case is simply not as you portray it.
The bother’s permission is irrelevant. He is not the one with the authority to grant permission.
Let me give you an example that is a little more concrete and one I have witnessed personally. We used to live in a rural area where trash pickup was optional. People could sign up with the waste management company or not. If you signed up you paid a monthly fee for any “reasonable” amount of household trash you put out on trash day. But one neighbor would always seem to have more than the normal amount of trash at the side of the road. One day I saw a relative of his who lives nearby drive up and drop off his trash at his relative’s house. Apparently they had made an agreement to “share” the one relative’s trash service. The trash company never complained because they did not know. They didn’t place strict limits on the amount of trash you could throw out because that would create a great inconvenience for people who occasionally did have a lot of trash of their own. So they trusted the customers to only put out their own trash.
Now perhaps you have more sympathy for trash workers than for “cold heartless ISPs”. But the fact is the trash haulers had to empty their truck more often, they incurred greater fees from the landfill, and generally were being taken advantage of. I call that immoral, and I think you would too. It is stealing a service.
Maybe the reason you don’t feel the same way toward ISPs is that you don’t believe they incur added cost for incremental service increases, but they do. And if it is immoral to steal from trash haulers it is immoral to steal from ISPs.
This is not theft. Nothing is being stolen.
Services are being stolen.
The OP’s brother is paying for a service which he can use up to a predetermined limit
I already addressed this issue in a previous posting. The predetermined limit is only authorized if it comes about through usage that abides by the terms of the contract. It is easy to imagine one person buying broadband service and then reselling that service to 20 or 30 neighbors (with wi-fi repeaters) on a somewhat limited bandwidth basis, and making a lot of money in the process - money that rightfully belongs to the ISP. Do you call that moral too? Or is moral use confined to sharing that does not involve the transfer of money?
The OP is compensating his brother by, presumably, paying for a share of that service.
He is compensating the wrong party. The one he should be compensating is the ISP.
Given that they live physically next door to each other, it’s not even remotely a stretch of the imagination to suggest that they have an extended ‘home’ to which they both have common access.
It is up to the ISP to decide if they want to treat the extended family as a single unit or not. They are the ones providing the service.
This is only a contractual issue at worst. It’s no different from a contract that says I may not park an RV on my parking spot but I go ahead and do it anyway. It’s a civil issue, not a matter of sin any more than exceeding the speed limit on an open empty desert road by 1mph is not a sin
This isn’t theft. Two people are clubbing together to pay for an internet service between them. They each get half of it and the usage limits are, in effect, twice as onerous for each of them. Perspective is everything in this.
You are right that perspective is important. A small injustice is not as serious as a large injustice. But it is the size of the injustice that makes it less serious, not the fact that it is a contract. You give examples of abuses that are small and inconsequential, and I agree - they are. But if that is the basis on which you are going to mitigate the OPs choice then say so. If the OP doesn’t use the Internet very much then the added burden on the ISP is going to be small - and perhaps even if the ISP knew about it they would choose to do nothing about it. As I said before, it is like shoplifting a few grapes from the supermarket. It is not a serious matter. But it stills sits at one end of a continuum that has large scale theft of services for economic gain at the other end.
