My thoughts on this matter are well articulated in Cem's recent post:
"Following a fight between Turkish and Greek internet users posting insulting videos and comments, and a wave of reporting on this by the Turkish media, YouTube is now apparently blocked by Turkish ISPs through a court order. While I find the entire back-and-forth by the nationalists in both countries in poor taste, I am shocked and disturbed by the decision of the courts."
The court decision does no good to anybody. The law that caused it is in progress to be changed. And it will be.
