It's like you say and normal provider do seem to make money somehow even at low rates.

So you would aks yourself is it really needed to put in crazy ratio's in term ?
When offering free incomming sure there will alsways be users that use it more compared to other ones. Like any business you have products that make lots of money but you also have lots that make little money. If a supermarket would take out all the products they make little money on or just a bit it would get really empty. They need those products also so customers will buy the more profitable ones.

The same with ratios. By having them you scare away customers that might nog even go over these ratio's. On the other hand you will have customers that will go over it if you don't have them. The trick is to have just a few of these customers and the rest will compensate for the few.

But by choosing ratio's and crazy terms you scare away customers that would normally not go over these ratio's but just because they are there the might not choose your service.
