You have that on mobile subscriptions usually, heavy users pay more and low usage users are not subsidizing them.
I take you are fine with paying 10x or even more for your no oversubscription Internet connection then?
Oversubscription is not gambling. The way it works after your last mile connection is that ISPs look at link usage in their network, city level distribution, city to city, transit, peering, etc, once it reaches 60-80% utilization at peak you start looking at adding more capacity. Bad ISPs (most US ISPs) will let this go too far though.
That's not the same thing. A more adequate comparison would be to say that you promised 30 people they can have a burger, but can only produce 5 burgers per minute. If everyone show up at exactly the same time, you won't be able to satisfy them all (they'll have to wait). But overall you can consider that the probability of such thing happening is small enough to take the "gamble".
It might be if traffic had sudden jumps of like 30%, but it doesn't and there is headroom available. Traffic increases slowly over time and you have plenty of time to upgrade your network.
