The PSPP project (originally called "Fiasco") was started so as to allow computer users to avoid the ethical problems imposed by SPSS. Under the terms of use of SPSS, not only are users forbidden from copying or modifying the program, but they may only use the software for a limited period of time. In later releases, SPSS has a built in
digital rights management , which allow the program to run for about 6 months, after which time the licence "expires" and it will refuse to work until the licensee pays more money.The author of PSPP considered this to be ethically unacceptable, so decided to write a program which would be functionally identical to SPSS, except that there would be no licence expiry, and everyone would be permitted to copy, modify and share the program.
