"Free software" is a term of art in the software industry: https://en.m.wikipedia.org/wiki/Free_software

The definition on that page is accurate:

Free software "allows users to run the software for any purpose as well as to study, change, distribute it and any adapted versions. Free software is a matter of liberty, not price; all users are legally free to do what they want with their copies of a free software (including profiting from them) regardless of how much is paid to obtain the program."
