I would not be surprised if someone in the government told then to start cutting off Syrian users. Of course, any attempt to block Syrian IP addresses could be circumvented, with proxies, which does not violate US laws, but might break Syrian laws.
Someone doesn't want truth coming out about what's going on in Syria; Youtube has TERMINATED the Syrian Arab News Agency channel on that streaming service.
UPDATE 12:54 PM EDT -- Youtube has now also shut down the Syrian Ministry of Defense (MoD), and the official account of the Syrian presidency.
Apparently, the powers-that-be in the US and Israel want information from inside Syria cut off.
Of course, Youtube covers their censorship by claiming a Violation of their Terms of Service; the cover-all they use to try to scam the public into thinking their censorship is somehow justified or noble. In this case, it is not.
The Syrian Arab News Agency is an official, state-run news agency covering events inside Syria. Perfectly legitimate news by a recognized media outlet.
This shows yet again that people whose interests depend upon the silencing of truth, wield extraordinary power to shut down the truth. They get away with it because, so far, they have not had to suffer any consequences for shutting down the truth.
In my opinion, it's time that Youtube starts suffering consequences . . .
