Freeware is any software that is distributed for use at a price of zero. However, freeware may not be "free software". The Free Software Foundation defines free software as software that gives its users the freedom to share, study and modify it. It has no copyright or other restrictions for distributing, modifying and using the software in any way.
For example, a software developer may choose to make her software available for download and use on her website. This software may be freeware if downloaded for personal use but commercial use may require a fee. In either case, if it is prohibited to freely distribute (for any purpose) or modify the software, then this freeware is not free software.

Free Software and Copyleft
Copyleft is a concept that allows free software advocates to use copyright law to further their objectives. The idea is to let users freely copy, modify, create derivative works from, and distribute software (or any creative work) with the condition that all derivative works must be released under the same license. The "share-alike" provision of Creative Commons licenses uses this principle.
