I don't see how that implies they won't try. From everything I've seen before, the neither lawyers nor judges tend to have a solid understanding of technology (lawyers might know the parts that will be helpful to them in their current cases).
There's a number of Linux developers living in the USA. I wouldn't be surprised if any live in the Chicago area.
They sell the OS to Illinois residents.
I have paid for Redhat just once. Since then ubuntu FTW
It's possible for Ubuntu too. Dell sells Ubuntu laptops to Illinois.
