An artificial speed limit is, be definition, a data limit. If you have X time and Y bytes per time (artificial limit), then you cannot get more then Y/X bytes.

An artificial speed limit is, be definition, a data limit. If you have X time and Y bytes per time (artificial limit), then you cannot get more then Y/X bytes. Now obviously it's limited by the technology to some amount of Y bytes/time, but that's accepted. When it's limited by policy to lower than that, it's no longer unlimited data.
