2 years of almost 24/7 daily death counts by the media. Non stop fearing mongering and doom by the talking heads. Mandates and other restrictions. Then Russia invaded and the news never talked about it again. Then all other restrictions were lifted.
Personally I think the narrative was simply collapsing. Even for normies having 3 vaccines and still catching covid makes absolutely no fucking sense.
Only two possibilities:
1 - some elites decided to pull it because it was getting too disturbing
2 - they already planned it to be pulled at that time
It was working en masse, there was no reason to pull the control system, makes no logical sense, so it must be an irrational human decision
