Here are two excerpts
"The mechanism that establishes computing you can trust is not any different from that which regulates a modern democratic society. It essentially rests on the right to vote, associated with access to objective information. Free/libre software, which, in a global computer base dominated by Microsoft, is gathering momentum, is the only one to follow these principles: its code is accessible to everyone and its modifications are collectively decided on by a community of developers. The installation of a backdoor by the NSA within the source code of a free program is theoretically not impossible, but it will always remain much less likely than it would be within a proprietary program, whose code is kept secret."
"That said, technical solutions have their limits. What we need is political awareness, both at the governmental level and at the individual level. This choice is going to require some efforts from each of us: proprietary software programs have for years aimed to infantilize our relationship with IT, on the assumption that the less we knew, the more we would behave like captive customers. Regaining control of one's computing is not easy, but it is an essential civic initiative. Everyone should try to give priority to free software."
