To me this is exactly the problem of our times and should not be trivialized. Were there too few gatekeepers of news in the past? Maybe, but the "new" problem is that it has become too efficient (IMO) to spread misinformation while peoples ability and tolerance to spend time on researching the facts has diminished. To say it another way, misinformation/obfuscation/misdirection are not new but the scale of it is and it is critical for us to come up with better solutions to deal with it than we have today. Our climate and our democracies depend on it.
