Re: Licence question - commercial usage.

[Alan Mead]

Piotr,

In a word, Yes. 

The longer answer is that PSPP is licensed under the GPL3 (or later) and you can read that document to understand your rights but compared to traditional commercial software your rights under the GPL are considerable (you can use PSPP as you wish, you are entitled to a copy of the source, you may modify PSPP, your rights to use PSPP will never "expire," etc.); see: https://www.gnu.org/licenses/gpl-3.0.html

The main things you cannot do are (1) share PSPP to others without giving them the same rights you enjoy (e.g., creating a commercial product from PSPP and refusing the terms of the GPL3) or (2) things that are illegal under local or international law (violating copyrights, trademarks, plagiarism, etc.).

The use of GPL'd software in commercial applications is described in this GPL FAQ which says that an author cannot both use the GPL and also prohibit commercial usage (i.e., that the GPL allows the user to decide what she will do with the software, including commercial or military uses): https://www.gnu.org/licenses/gpl-faq.html#NoMilitary
