(this page is part of the Family Guide to Digital Freedom, 2007 edition. Please do read that introduction to know more about the Guide, especially if you mean to comment this page. Thanks) Is it really needed, to make the world a better place, to make sure that only Free as in Freedom software is allowed to exist? Probably not,for the reasons explained in the chapter on software protocols and file formats: if only formats and protocols which are Free as in Freedom, that is usable without any limit or discrimination with many different software programs, were used, at least by Public Administrations, all or most the excesses and abuses caused by today’s proprietary software technologies would vanish without further effort.
