Information is like a living organism; it expands to fill the container in which it is kept. Put some life form (it does not matter which) in some environment, and it will instinctively probe the outer limits of its habitat. Knowledge is like this, too. It can be suppressed for some time, but in the end, it cannot be held back forever. It always disseminates in one way or another. No matter how effective propaganda, official lies, and ideological correctness may seem, they can never hold back the tide of truth for an indefinite duration.
