That's one thing that bothers me about security in general, that it's so super political and it's a bit hard to just be interested in the technical aspects of it without being sucked into political bickering to some degree (can't follow Twitter accounts of most security people for that reason). Of course, I understand that it comes with the field since many adversaries simply have political motives. Still annoying though.
I don't think much has changed, it's just that we see a lot more diversity than 30 years ago. Having grown up in East Germany, if I hadn't lived close enough to the Western border I could only have viewed East German TV and read East German newspapers. In the US you were (for the most part) not exposed to anything from Russia, and vice versa. Now more people get to see that the world is quite a bit more colorful, for both better and worse.
I don't think it matters all that much, because apart from passive news consumption, what would you actually do (that is impacted by the information)?
Meaning: it’s not all propaganda, with each side being equally bad and the truth to be found by triangulation.
