What is real agenda of Al-Jazeera in Muslim world?

If true, yet more disturbing signs that Al-Jazeera is more than happy to see itself as endorsing regime change in the Arab world and often backing Western military support to do so (via AlAkhbar):

Emails said to reveal dismay among Al-Jazeera staff over its “biased and unprofessional” coverage of Syria have been leaked by pro-Assad hackers.

Damascus – On Wednesday, the entire staff of the Al Jazeera network allegedly received an email instructing them to change their computer and email passwords.

Earlier in the week, the network’s server had been hacked by the self-styled Syrian Electronic Army, and some of its secrets were released to the media.

The major find to be made public was an email exchange between anchorwoman Rula Ibrahim and Beirut-based reporter Ali Hashem. The emails seemed to indicate widespread disaffection within the channel, especially over its coverage of the crisis in Syria.

Ibrahim wrote to her colleague saying that she had “turned against the revolution” in Syria after realizing that the protests would “destroy the country and lead to a civil war.” She went on to deride the opposition Free Syrian Army, which she described as “a branch of al-Qaeda.”

Ibrahim also complained about the attitudes of various colleagues at the channel’s Doha headquarters, saying some of them “have refused to greet me ever since the outbreak of events in Syria because they hold a grudge against my sect.”

Hashem responded sympathetically, saying he had opted to sit on the fence after sending the channel footage of armed men clashing with the army which he had witnessed while reporting from northeastern Lebanon. He said that after he submitted the video, he was told to return to Beirut on the grounds that he was exhausted.
In her response, Ibrahim once again protested that she had “been utterly humiliated. They wiped the floor with me because I embarrassed Zuheir Salem, spokesperson for Syria’s Muslim Brothers. As a result, I was prevented from doing any Syrian interviews, and threatened with [a] transfer to the night shift on the pretext that I was making the channel imbalanced.”

Ibrahim also spoke of how Syrian activists invited onto Al Jazeera use terms of sectarian incitement on air, “which Syrians understand very well.”

Hashem wondered in response where the channel’s head of news, Ibrahim Hilal, stood in all this. Ibrahim answered that he was “stuck between a rock and a hard place: the agenda and professionalism…”
