Arab public opinion and Syrian rebels

"About 90 percent of Arabs also share Al Jazeera’s support for the rebels in Syria." 1) That is now shown in the latest Pew Poll, and it is the most recent poll on the subject. 2) if 90 percent of Arabs share Aljazeera views on Syria, they would be in the streets daily or weekly or even any time when the only public show of support for Syrian rebels has been manifested by Salafis, and the show of support has been very scant. 3) If Arab public opinion is truly 90 percent in agreement with Aljazeera, why would Aljazeera be suffering from such dramatic decline in viewership?
