The 4 freedoms

The objetive of Stallman since then was to create a free operating system, based on his believes on Freedom. He said that all software must to have the follow freedoms:

• Freedom 0: The freedom to run the program, for any purpose. (It is somewhat stupid, but nowadays it must being specificated because this freedom is in trouble, as all the others)

• Freedom 1: The freedom to study how the program works, and adapt it to your needs. Access to the source code is a precondition for this.

• Freedom 2: The freedom to redistribute copies so you can help your neighbour.

• Freedom 3: The freedom to improve the program, and release your improvements to the public, so that the whole community benefits. Access to the source code is a precondition for this.
