their whistleblowing was somewhat silenced / didn’t meet the standard of “legal evidence” or something?
There were probably many people who realized that they don’t have any legal evidence, and could be exposing themselves to a defamation lawsuit, so they didn’t say anything.
When someone says “if many people were involved in conspiracy, someone would expose it”, there is a huge difference between “exposing” a conspiracy in the sense that you report a crime and call the journals, and “exposing” it in the sense that you privately tell your friends that something bad happens somewhere and they should avoid it.
