My theory is that they want to make us question the reliability of our own and others memory so that when we recall some of their crimes from the past others will shrug as a crazy old man. Some 1984ish destruction and refabrication of evidence could be going on. It is possible that all found copies of that KitKat or cereal packaging have been replaced or destroyed.
What my plan for the future would be is stashing samples of product packaging somewhere where a spy can’t find them.
I agree with this. We are being gaslit hard so that we don't feel confident enough to decorate our lamp posts when we've had enough. This is being done on purpose by purging evidence from the internet, and even from our personal computers. While it may seem outrageous to make that latter claim, it is absolutely happening.
I keep offline storage of key documents and stuff now, because it's happened to me several times.
