Why does software have EULA? [closed]

Question

This is the only product that I know that a consumer must agree to something that only lawyer can (something) understand. I'm sure car accidents kill more people each year than software accidents. But I don't sign anything like an EULA when I buy a car.

So why does software have EULA? Were there a bad accident that triggered the need for software companies to protect themselves? (and what was the first software that had EULA?)

[Update] Just to clear my point: I don't understand why software have EULA. No other product that I can think of does (not even gun)! So what makes software different that this product needs some sort of "liability limitations"?

By the way, Wikipedia says that "The legal status of shrink-wrap licenses in the US is somewhat unclear."

Answer 1

The difference is that you are purchasing a license to use software, not the software itself (which the software company still owns). The EULA stipulates the method with which you can use the software. Similar agreements are in place when you rent things (e.g. a home), lease equipment, etc.

Answer 2

An EULA is designed to be a contract that conveys or limits “usage” rights, hence the name End User Licensing Agreement. It has nothing more to do with a copyright than the mortgage loan contract that I have with my bank. That is why the legality of shrink-wrapped licenses is questionable. It is a contract that you do not get to read until after you purchase a product. It is clear from many responses here that the vast majority of people have not wrapped their heads around the idea the copyright does not extend to “usage” rights.

One responder wrote “Actually, the book is yours but the rights to the book are not. Just as in software, you purchased the physical media, but are bound by law on how you can use it.” Nothing could be farther from the truth. There is no law that restricts how you can use the book. Any restriction on usage would have to be agreed upon by you and the retailer as part of the sale.

Consider that in the absence of copyright, the copying and distribution of books would be perfectly legal. A book would be typical tangible property and nothing more. Copyright limits your ability to legally copy and distribute the content of the book. No additional agreement is necessary. Copyright in no way dictates how you can use your book and copyright law does not convey to the author the power to convey, limit, or negotiate “usage” rights. The only way that they can limit usage rights is through a separate contract that would have to be completed as part of the sale or rental.

There was some confusion regarding the GPL. The GPL is not an EULA. It is a copyright license that permits copying and distribution of the content so long as you comply with the restrictions of the license. In absence of the GPL (say you choose not to accept it), you can still use the software, but you are restricted from copying or distributing the software by Copyright Law.

EULA exist for various purposes. Companies that develop software want to negotiate a position that puts them at the least risk and gives them maximum leverage.
