That explanation doesn't explain why there are limitations though. That explains why the trial version has limitations which makes perfect sense, but just because one has it doesn't mean the paid version needed to have it. As you said it was mainly do to "Hit and Runners", but in this case people paid which fulfilled the thing that people were afraid they would get. The problem I see with the limitations is that it favors people who sit there and will constantly download versus those who do it in bursts. Since the ones who essentially keep it running will get more tokens over time due to it constantly refilling where as someone who does it in bursts (likely most users) will have to wait for the refills more often. Over a week's time the one constantly downloading could max out the amount of tokens while the one who downloads in burst could maybe hit half that before it "resets"
