One the one hand, there's the critique that media institutions are becoming more commercialized, dumbed-down, and turned in to infotainment, where serious discussion and inquiry is thrown out the window in favor of shouting matches and sensationalism.
There's another critique that media is in service or left-wing, right-wing, capitalist, or corporate special interests and parrots the party line.
Yet another critique is that the media doesn't give marginalized voices enough air time.
So when you say "everyone is losing confidence in the press" that may be true in general, but different people are doing so for very different reasons.
The grandparent comment seems to be a critique of the third category, where they seem to want the mainstream media to give more air time to conspiracy theories in direct contravention to the consensus of the scientific community: which is that SARS-CoV-2 came from nature, not from a lab.
My actual criticism was closer to your first category: "where serious discussion and inquiry is thrown out the window in favor of shouting matches and sensationalism"
But thank you for demonstrating my point by re-collapsing all four questions into one.
Sensationlism is squarely on the side of the conspiracy theores.
Read past the "a)" because those are way more important and may be discoverable.
(1) either confirmed, debunked or unproven;
(2) either originating from an authoritative source, originating from a non-authoritative source, or of unknown origin;
(3) either promoted, downplayed, or ignored by any particular media outlet.
These are, again, three orthogonal axes that you are implicitly, and stubbornly, conflating.
Anyone sensible is not even asking themselves if "conspiracy theories" are true. They're asking themselves where the hell they come from, why are they so contagious, what prevents societies from effectively containing them, and what are the long-term effects on our societies' health.
Or maybe anyone sensible is looking to profit from the confusion, and I'm a raving lunatic... Have you considered becoming one yourself?
