They coded a program and they want their program be used in the way they like it.Their program is not hold a monopoly in the market so if they don't like their license agreement, you are free to use a rival program whose license agreement fits better to your demands.

They are not alone in their policy either. Many software vendors put everything they can hold against customers in their license agreements. Many companies are even using these agreements as "weapons". For instance say you purchase 1000 Windows license from Microsoft and spend a lot of money to design all your company's system based on Windows. Then you decide to host your internet site on linux which then angers Microsoft. They pay your 1000 Windows license fee back and ask you to stop using Windows anymore. Since you can't do it, you agree to host your server in a Windows NT enviroment instead of linux or your whole company network will go in jeopardy.

The legal validity of such license agreement items (mostly with respect to consumer laws) is another hot discussion. This discussion is blur either because comments would change according to the law system you are discussing as every country can have a different attitude on this legal issue. The truth is such things are going on everyday in the software market.
