Being ethical goes hand in hand with being trustworthy. For as long as anyone can remember from the Conservative side of the isle, the media has been more and more unethical. This has lead to a concurrent reduction in the trust that we, the viewing public, place in the reporting done by said news organizations. Now that we can, as the saying goes, "fact check their a**" with that wonderful medium that is the internet, we can see that the emperor has no clothes on, and hasn't for quite some while.
Legacy media hasn't caught on, in most cases, and those that do understand what's going on are trying to fight it, with McCain-Feingold being one notable example.
It's fun to watch, because the fall of National News is a good thing for those of us who want our freedoms back. Now, our voice can be heard, because legacy media no longer has a lock on what We the People can see and read.
