Go on. Explain how the physical limitations change anything I said. I don't deny that there is a limit to the amount of data a tower can handle at once. I'm saying that previous use of data is not a justifiable reason for throttling one person but not another. What if I use a 100 gigs on a tower that never once gets saturated, and then I take a trip and get lost and need help? Is my data use less important than the person who lives in that town who wants to settle a debate about who acted in a movie simply because I've used more at another time on another tower elsewhere? Since the carrier doesn't know the value of the information being throttled they either need to throttle everyone so it's clear that their network is congested, or they need to compensate those they throttle. To put it another way. Throttling data is like bumping a paid passenger. Everyone has a equal expectation to get where they paid to go regardless of how many flight they took that month. It's one thing to delay everyone, it's another thing to forcibly pull someone off against their will.
