There's a journey that every hypothesis makes on the route to becoming "information", and that journey doesn't start at top-down official recognition. Ideas have to circulate, get evaluated and rejected and accepted by different groups, and eventually grasp their way towards consensus.

I don't believe Trump's or Kennedy's ideas about COVID and medicine are the ones that deserve to win out, but I do think that top-down suppression of ideas can be very harmful to truth seeking and was harmful during the pandemic. In North America I believe this led to a delayed (and ultimately minimal) social adoption of masks, a late acceptance of the aerosol-spread vector, an over-emphasis on hand washing, and a far-too-late restriction on international travel and mass public events, well past the point when it could have contributed to containing the disease (vs Taiwan's much more effective management, for example).

Of course there's no guarantee that those ideas would have been accepted in time to matter had there been a freer market for views, and of course it would have opened the door to more incorrect ideas as well, but I'm of the view that it would have helped.

More importantly I think those heavy restrictions on pre-consensus ideas (as many of them would later become consensus) helped lead to a broader undermining of trust in institutions, the fallout of which we are observing today.
