Since this story was in the business section of the New York Times, I suppose it means people know that Al-Jazeera is, you know, a business. People are worried that it has a bias - which of course it does - and that all it gives them is propaganda.
To which I say: where have you been? It's not shocking that media outlets have a bias. Figure out what the bias is and try to filter it out. If the station is providing a useful service, in this case coverage that no one else has, watch it and think about what you're watching. Be a discerning consumer and decide for yourself what is and is not true.
