Actually, Youtube has been censoring content since (iirc) at least before 2010 - there were many researchers who I followed who just got deleted by Youtube at that time (and ever since). It is more common for accounts to be sandboxed and reach restricted, so they are definitely censored without them even realising most of the time. This is the norm for Youtube and occurs on a large scale. I proved this by viewing my videos and comments via Tor - the anonymous browser. Many of my comments are invisible to the wider world, but visible to me. This has been the case for probably over a decade.

The pattern you described with Fauci is the EXACT same pattern that occurred with Morris Fishbein, ex head of the AMA: https://rense.com/general19/enemy.htm

He was putting up posters of people who were treating cancer using non toxic methods, saying they are public enemies and ruining their careers (hurting patients in the process). Meanwhile, behind the scenes, he was trying to acquire the patents on their recipes in order to steal their thunder. In general, these people are obsessed by personal power, so they crush anyone who has it in an attempt to take it and use it for themselves.
