I believe that's spot on, and it's essentially the same with newspapers and TV, at the very least today. 30 years ago, there was only one truth, and it was spread via mass media. Now, there are competing narratives, both in mass media and on the Internet, and everybody picks and chooses what fits into their understanding of the world.

And the degree to which you can observe and influence what is said. If you force people to adopt secure communication en masse, you lose a lot of possibilities. I don't know how much this is a concern for governments, but I don't think that they will be able to win the crypto wars, so pushing people into secure comms by overreaching today means they will have a much harder time tomorrow. But maybe they won't be in charge tomorrow, so it's not really their problem.
