Ad hominem notwithstanding, I don't take anyone to be an idiot. But having experienced, time and again, that Verizon employees are rude and have zero interest in helping their customers, and having experienced, time and again, that T-Mobile employees actually treat their customers pretty well, I have to say I disagree. Yes, both Verizon and T-Mobile exist to turn a profit, which is therefore their motivation for what they do. Neither of us is an idiot for stating the obvious, since you said the same thing in your post.
Nevertheless, I think there's a big difference between a company that profits by screwing people over and a company that profits by treating their employees and customers right. Both have the goal of profit in mind, sure, but one is moral and one is not. Correct me if I'm wrong, but I gather that you have the "companies are greedy, that's all there is to it" mentality going on, but I think it's worth keeping in mind that businesses are run by people who make these decisions, so how businesses act are a reflection of how the management acts. It's easy to vilify businesses, but I don't think they all deserve it.
That is, of course, unless you think being successful is evil in some way, in which case 1. I'm not sure how to help you go anywhere in life, and 2. I'm not sure why you're on an Apple forum.
