LinuxFocus.org:While the big companies were trying to sell expensive licenses, the Free Software Foundation was trying to spread
the concept of free software. Free meant freedom to run the program, to modify the program, to distribute copies
or modified copies for the benefit of the community, but not always for free (you may charge for it). If you want to
learn more about it, just go to http://www.gnu.org.
Many people were attracted by this philosophy and at the beginning of the 90's there were different flavors of free
Unix: NetBSD, Linux...
Today, about 50 commercial or free Unixes are available (may be more!).
