A common argument (that you also make) is that if you're on the inside, you obviously know better than those on the outside. There's a lot of reasons to believe that isn't true.

First, you may not have the right training (e.g., media studies, media economics, privacy). Second, you favor your coworkers because they are your friends. Third, the positive news and justified criticism of external critics is widely shared internally, but the points that are appropriately critical are much less shared. A single flawed external article can lead to defensiveness, making it that much easier to dismiss tens of other appropriate articles.

More poetically, it's like the Three Blind Men and elephant. The conviction of the blind men is so great, but their closeness leads to a misplaced confidence that they know the answer:

I call this effect the "truth distortion field," and liken it to the Facebook friend filter bubble:
