Truth is always the enemy of power. Exposure of power's motivations, depredations, and corruption never serves power's ends. Truth is often suppressed and those who disclose it persecuted. Any illegitimate government (currently, all of them) that fails to do so risks its own termination.
What if, instead of suppressing the truth, a regime could render it irrelevant and not have to worry about it? That prospect is the Holy Grail for those who rule or seek to rule.
Imagine an announcement to the populace: We rule you and every aspect of your life. Your wishes, desires, and plans are immaterial to us. You will do as we tell you or you will be severely punished or eliminated. Our sole end is power and we will be its corrupt and criminal beneficiaries. You are our slaves.
