It is easy to identify a Free Software project. It includes the term “Free Software” in its website. Open Source projects created by corporations, by hackers who reject the ideals of Free Software or by developers who do not know the difference NEVER include the term.
There are of course many others and please comment with your favorite ones, but in fact, if you try to think of a recent notable FOSS project and check out its website you are most likely to find it is an Open Source project rather than Free Software.
For example, Apache, Lighttpd, MySQL, PostgreSQL, Python, Django, Drupal, Firefox and others.
For those of you who wonder what the difference between Free Software and Open Source is, I recommend the following article: http://www.gnu.org/philosophy/open-source-misses-the-point.html
There can be several reasons why this is the state of Free Software. I believe one of them is that there is no economical energy behind Free Software.
