No idea on the darpa thing, haven't read it or heard of it. One man or one organizations opinion don't invalidate data though.

Why would the CDC director admit to 75% of fatalities are from people with four or more comorbidities during an interview? Sounds like a misspeak, that figure is from the 36 vaccinated fatalities. But you keep ignoring this clarication. There is solid data to back this up and NO data to back up 75% overall. So it would be nonsensical to state otherwise.

Why would the CEO of Pfizer make a statement that they're MAY be some protection with this new varient and maybe some with booster and why is Pfizer having the video taken down everywhere? Shots are specific to strains...right?
Because research is ongoing. Making the statement that an additional booster is effective without testing to back this up is irresponsible. As far as them getting removed, covid misinformation is rampant (see your question 1 above) I would imagine automods remove a ton of stuff in general. No platform wants to get sued because someone posts trumps recipe for curing covid by injecting bleach and someone dies.
