The 4 freedoms, again

4 Freedoms for the Public :

  1. Freedom to run the program, for any purpose

  2. Freedom to study how the program works, and adapt it to your needs

  3. Freedom to redistribute copies

  4. Freedom to improve the program, and release your improvements

Nothing really left for the author to control : the software tends sometimes to deliberately become a "moral person" which interacts with the users and contributors without intervention of the author.
