You still have unlimited access and unlimited download capability. Your connection is already limited to a certain Mbps, so throttling it down to 50Kbps doesn't change that. So their argument would be that they don't mean an unlimited Mbps ... that is impossible to provide, they mean unlimited consumption. Limiting a user to, even your 1Kbps still provides for unlimited consumption, just veeeeeeeery slowly.
Okay, I get it. It's Friday and you're making up for the fact that dadkins seems to be sleeping.
