The reason that the 'official' word is getting and less credible is that the confidence of those speaking those words is at the point where it really doesn't matter whether anyone believes it or not. I'm sure that Solzhenitzyn must have declared somethng like this n his writings "we know that they are lying, they know that we know that they are lying, we know that they know that we know that they are lying, yet they still continue to lie" (quoted from memory, so if not exact the sentiment is there). They don't care. There is no consequence. "Kicking sand in our faces", "Pissing on leg and telling us that it's raining". The power is being consolidated now.

Besides, everyone knows that Ms Heche died from climate change. Or long covid. Or long covid caused by climate change.
