According to this news tidbit, YouTube should be accessible to the Pakistani public in a matter of day with only videos of material deemed blasphemous and sacrilegious blocked . So why didn't the Pakistani government do this in the first place? Then there is the question of who will determine which content is Blasphemous or not? Will Youtube videos of religious practices of other sects be banned because the majority Sunni faith considers them Blaspehmous? Will potentially embarassing videos of politicians be blocked as well under this rule?Who will implement this ban (The PTC or the ISPs)? So while I'm glad that YouTube is back, this newest development is nothing but another can of worms in my opinion. As for Facebook, it is still pending a court decision about its future in Pakistan.
P.S. Be sure to check out this post on how banning Facebook is like the Hijrat to Medina. It's mind boggling how some people can come up with this stuff. Ahsan (Five rupees) summarizes it quite nicely here.
