Well, commercial licenses are actually quite simple. All they boil down to is: "You pay us money and redistribute our components". There might be other conditions: a percentage of gross from hardware sales, fees for each developer working on a product, etc. But in general they are fairly simple to comply.

Besides, commercial licenses are something business is accustomed to deal with, paying for stuff to produce other stuff is the core of our economy.
