Yeah, well, to fair....
"AT&T, on the other hand, has argued that not throttling data speeds for bandwidth hogs would result in slower download speeds for all customers (and to be fair, other telcos have made the same case)."
To be fair, they and their ilk brought it on themselves by using a common word like "unlimited" in a limited sense in their marketing. The man in the street sees "unlimited" and takes it at face value. Unlimited data. The ISP meanwhile, wriggles out of it by saying the connection time is unlimited, not the data throughput and the customer feels ripped off. (AOL were good at that one in the dial-up days too)
Of course, we all know that words can have many meanings and nuances but marketeers are masters of mis-leading advertising and using words in unusual ways with the intention of deceiving the punters while holding their hands up in all innocence that "of course we didn't intend that, we had no idea people might read it that way, none of our focus groups told us that!"
