Whenever you assert something that sounds conspiratorial, the response by normies is almost always about "wouldn't we have heard something by now?" and "where are the whistleblowers?"

Both assume a media that's honest and seeking truth, neither of which have been true for a long time, perhaps ever. Conspiracies can easily be kept under wraps with suppression. Deplatform or never allow in the first place, anyone that can expose the conspiracy and that's it. Even if you get whistleblowers, you can always play the game of discrediting the person instead of addressing the charges.

There have been and continue to be lots of conspiracies. We just don't know about them because the authorities won't let them out. It's only on the fringes that you'll get even a hint of them.
