>But, what you really don't seem to be getting is that they do have a responsibility not to harm us. That's why there is a legal cause of action known as "tortious interference". I sincerely don't know how to make that point any clearer. Perhaps researching that term a bit might help. Yes, yes, reading up on that is probably a good idea. I am not a lawyer... but in the case of a mail-filtering company blocking emails that their customers have asked them to block, they are harming the senders of those mails. That is a direct result of what their customers are paying them to do. Or ad-block programs- really, it's exactly the same thing; what the ad-blocker does for the user does harm the advertisers. There's many, many places in the free market where helping one side of a transaction hurts the other. That probably means that "tortious interference" is more complex than you are making it out to be. There are a lot of situations where helping one party necessarily hurts another, and helping one party over the other is generally not illegal.
