The licensor usually has the right to revoke the license to use. Even the music and movie industries haven't been so bold yet, although it seems that even they are now pursuing options on how to severely restrict use. The quality of software has not been improved by current warranty protection. If anything, it can fairly be argued that the quality of software has declined significantly during the past decade. This decline in quality is allowed to happen due partly to the fact that consumers have no remedy with software developers.
Shrinkwrap licenses commit consumers to acceptance of terms before the product has even been used.
This is unheard of with any other product. License terms should not require acceptance before the software has been tested by the buyer. Buyers should have at least the same rights with software as they have with other products. In fact, it could be argued that buyers should have more rights with software. Software has the potential to destroy or corrupt data, and most current license terms hold the software developers harmless in such cases.
