The legal status of the EULA is very different in the US and the EU. In the US the EULA is concerned more as a contract whereas in the EU it is followed more as guidelines. Some consumer rights protects the european consumer as well. For instance Kindles EULA was declared a partial nullity since it broke some consumer protection rights.

And here in Finland I am allowed to decompile any software I bought if I feel that I need to improve the software, and copy it to my family and friends. Even if the EULA states otherwise.
