As a rule of thumb you can use any news service as a source of information as long as you don't use it for information about the government of the country where it originates from and the major adversaries of that government or country.
That makes reading the news and staying current a lot harder and probably will require you to gain language proficiency beyond what you can get at through the English language press.
We can debate whether it's a meaningful or indicative tie. That seems like a live debate. But "the BBC was a mouthpiece for the Iraq War effort" isn't germane to this discussion. I agree that it was too. Believe it or not: it is possible to (a) oppose the Iraq War, (b) believe that it was disingenuously sold to the American and British people through media manipulation, (c) oppose the NSA, and (d) still think Wikileaks is suspicious and untrustworthy. I fall into that a-b-c-d bucket.
I don't have any examples in mind but I feel like the BBC has never held back on criticizing the government/people in power, and doing reports on gov't scandals and the like.
