The problem is there's simply not enough capacity for _everyone_ to use their 10 Mbit connection at the same time. That's a necessary property of efficient packet-switched networks. As a result of this, people who use more total data generally incur higher infrastructure costs to the provider than those who use less; even if those two groups of people have the exact same link speed.
