Having a multitude of sources and letting people choose as a solution presupposes that people have the time and the inclination to fact-check and are capable of evaluating news and sources critically. If I see how much time it takes to carefully fact-check some of the nonsense articles that have been doing the rounds recently, it would be a full-time job just to stay reasonably up-to-date. This is why people have been sourcing out the job of fact-checking and editing to e.g. newspapers in the past. I also very much doubt that the majority of people are capable of critically evaluating news items. Some of the discussions I've had recently, where people wouldn't change their opinion even when confronted with clear-cut evidence, haven't helped convince me otherwise.
