This is why Red Hat Software, founded in 1994, created the "Official Red Hat Linux" and is able to sell this normally "free" software. Because the software's license encourages modification and customization, it is nearly impossible to support. Over the next three years, Torvalds received these modified versions from the other programmers and incorporated many of the changes into the baseline version and released Linux version 1.0 in 1994.Ī common concern for end-users who wish to use open source software is the lack of a warranty and technical support. Many of these users were programmers in their own right and made modifications to the source code that Torvalds had included. A lot of people around the world downloaded Linux and began working with it. Torvalds released version 0.02 of Linux under the GNU General Public License, which provides a good legal definition of open source software.
