When they claimed that vaccinated people couldn't carry the virus, people lost their jobs.
From your link (emphasis mine):
Centers for Disease Control and Prevention Director Rochelle Walensky is touting new CDC data that suggests people who have been fully vaccinated almost never carry COVID-19.
Fully vaccinated people almost never test positive for COVID-19
Oh and even:
Fully vaccinated people almost never test positive for COVID-19
When I heard experts talking about vaccine, I heard them saying "significantly reduces the chances that you will end in the hospital needing intensive care". But that is too complex for Joe Sixpack. Joe Sixpack says "even if you get vaccinated, you still can get the virus" The fact, that the probability is much lower, is lost to him. So you simplify the message to Joe Sixpack's level: "get vaccinated and you don't get sick". To which Joe Sickpack says "that's not true because my cousin's dog's hairdresser was vaccinated and got sick anyway. Your experts are liars and full of it."
So what exactly should CDC say to not "abuse their role/power"?
