Please note that Verisign has a profit margin of 50%. Ie, 50% of their revenue becomes pure profit. This is an insane level. Apple is at 23%. Facebook at 35%. Profit margins that high only come from rent seeking backed by the full force of the law.
How do you decide what profit margin is acceptable? Is it okay for a company to have 3%? 76%?
I don't see that for Verisign, they're just rent seeking off domain. Their profit should probably be capped AT&T style back in their monopoly days with heavy regulation.
