For example, RedHat, Cisco, Suse (Novell), Alfresco, Wordpress, Drupal, etc. Can sold their Free Software project.

You can have it free. And it's ok. But having success is possible too (recheck my examples).

You can refuse to pay. But, if you want support : $$$ for value++. (you just buy the brand)

I wish people would tell you what's wrong with your comment instead of downvoting you into oblivion. Sorry, sometimes HN sucks.

There's a great difference between selling access to your software and selling your project itself, i.e. the copyright assigned to your code and/or logos, trademarks, etc.
