In the 90s, you had a few people on the internet, who knew all that stuff, but because the internet was "hard", they (we?) represented the majority of internet users.

Now, they/we are all still here, knowing all the ways of private communications, protocols, etc. + all the new, better ways to communicate privately and securely.

The only difference now is, that a few billions of "normal people" joined us online, and they don't know and don't care about all that, so the propaganda just moved from TV to facebook and youtube.
