Re: Erm
"Now people in the know have said 'don't rule out the lab leak theory', which goes against several years of media narrative."
It may go against "media narrative", but it doesn't go against the science. Science has and continues to look at all the possibilities with varying degrees of confidence based on the data that and is being collected. Maybe you missed that word, science, in my comment and the quote I posted?
As for your other comments, marketing can always find "someone" to say what they need to be said, and then be distorted and "simplified" by "the media", eg "it must be a lab leak" is pure speculation. It *might* be a lab leak is science, where might is is a quantitative estimate based on evidence and experience. Maybe one day we'll know for sure, but if it really was a lab leak, China will sit on that for long as possible and without a major change in policy and/or regime there, long after we are all dead and gone.
"People in the know" who actually DO know what they are talking about, have not ruled out any of the possibilities. How those possibilities have been weighted has depended on available evidence, bit not ruled out. It's often a good idea to listen to an entire news report or read an entire news article because sometime "inconvenient truths" are often stated below the first couple of paragraphs because they don't match the publishers narrative. At least in most case, they actually publish the truth as far as it's known in most case, they just try to bury it far enough down that those of a short attention span will not see it.
