No it wouldn't. The actual usage has a negligible impact on the expenses for infrastructure. Most people barely use any bandwidth anyway. Even on 1 Gbit/s lines the average bandwidth used is in the single digit Mbit/s. And the usage basically doesn't differ if they have a 100Mbit/s or 10Gbit/s connection. Also those countries where data caps are still a thing are generally those with the worst Internet.
