Christine Kelly, spokeswoman for the Conseil Supérieur de l'Audiovisuel (CSA), the government broadcasting authority, said: "Why give preference to Facebook, which is worth billions of dollars, when there are other social networks that are struggling for recognition. This would be a distortion of competition. If we allow Facebook and Twitter to be cited on air, it's opening a Pandora's box. Other social networks will complain to us, saying 'Why not us?'"
This doesn't mean that they are blocking the use of those social networks. It gives a chance to other social networks to gain more recognition.
