In this discussion and the older threads he links in there, Bedford basically rules out an 'engineered' virus, does not rule out a lab leak, but leans towards zoonosis (pathogen jumping from animal to human).

Here are Thread reader links for the older threads he references:

The other links you provide are rebuttals of particular arguments, but in no way settle the entire question. Knowing that bits of HIV weren't inserted into SARS-CoV2, for example, tells you nothing about whether this virus may have emerged from natural selection experiments in the lab. There are good arguments on both sides, but Twitter, in particular, seems stuck on the pronouncements of early 2020, when nobody knew much of anything about the virus and a certain prominent politician was speculating wildly, thus setting up a left/right polarization over what should be a factual debate.
We need to stop this hostile form of "scientific debate" where one person's opinion is held up as "the science", while all other voices are dismissed as fringe.
This is a very strange word. When I read history of science books, this word was almost never used. Change of scientific consensus is not uncommon in the history of science. Scientists disagree with each other, debate with each other, but they don't claim they debunk each other.
I don't believe people use this word in good faith. It seems to be politically loaded power grab.
I don't think very many people think very deeply about the meaning of words, and how subtle changes in the ones that are chosen can influence the collective consciousness. A lot of people even seem to strongly dislike the topic being mentioned.
They'd probably prefer that you didn't notice they were doing this.
If it was bred in a lab via humanized mice engineered with human ACE 2 receptors, would you consider that? What about forms of "no seeum" splicing?

Where are all these animals in the wild (since the lab theory has been "debunked") with SARS-CoV-2?
I'd imagine we'd have found tons of them by now, right?
I don't personally doubt it's a conspiracy theory but would you clarify exactly where "American scientists" debunked this - is it in the link you provided, it's not clear, it appears to only deal with claim 2?
