The same as Level3 charges more than others (even though not as extreme as DTAG) because they think their pipes are premium.
I mean, yeah, sure, it sucks for the customer. What I don't understand is your implication that this is Hetzner's fault. Both sides could accept the other side's conditions, neither side did, all of that is "just business".
What isn't "just business" is asking much higher prices than the competition for the same kind of service and expecting customers to buy it. And if you find that there are customers who do buy anyway, that's a hint that you are dealing with a monopoly situation, which is appropriately described as "holding people hostage".
