No, that's a fallacy. If I find an apple on the ground at the supermarket, it is evidence that there are apples at the supermarket. It is not evidence that there are no apples at my friend's home where I found no apples. I just didn't check the refrigerator.
The linked thread says, precisely, "Wuhan--a city 1,000 miles from nearest wild bats with SARS-like coronaviruses". And that is not correct.
I'm saying that there's no evidence of any bats closer to Wuhan with SARS-like coronaviruses. And I'm saying that, while it's indeed possible that these hypothetical bats exist - just as it's "possible" that COVID was transmitted to Wuhan via a teapot halfway between here and Mars; that COVID unicorns exist on an undiscovered island somewhere and one sneezed particularly hard and its germs ended up in Wuhan; or that COVID spontaneously formed one day on the apples in your friend's refrigerator in Wuhan - it's, again, not spin for a scientist to refrain from couching everything in uncertainty because of the infinite evidenceless hypotheticals that might disprove it; this is how every single positive statement in science functions. It is indeed correct, scientifically speaking, that there are no apples at your friend's home where you found no apples [based on all available empirical evidence]. And it is indeed correct, scientifically speaking, that Wuhan is 1,000 miles away from the nearest wild bats with SARS-like coronaviruses [based on all available empirical evidence].
That's not all you're saying, though. You're extrapolating from that fact to argue that bats closer to Wuhan with SARS-like coronaviruses are therefore unlikely to be present.[1] And no, that's not correct. Viruses span continent-wide gaps all the time, we don't need any special evidence to cite that as a possibility.
[1] Or more specifically, that they're less likely to be present than a man-made descendent. This is how you can spot a poorly justified argument. You're skipping a step and inserting an assumption in exactly the way you need to address a hole in your argument. Again, I pointed out upthread how I can spin exactly the same facts in the opposite direction (IMHO more convincingly, though logically no more sound).
That said, I'll bite: if there are bats with SARS-like coronaviruses closer to Wuhan, I suspect that the folks in Wuhan who've spent the past 15-20 years studying SARS-like bat coronaviruses, "sampling thousands of horseshoe bats in locations across China" [0], probably would have discovered the ones right on their doorstep, more probably than ones further afield. So sure, yes, I'd wager they're not all that likely (though not impossible)! But, again, that's neither here nor there to my overall point, which is that your accusation of spin on Ebright's part is unfounded and scientifically illiterate.

You added the word "candidate". I agree with what you wrote. Your framing doesn't imply an incorrect conclusion, though it also lacks any rhetorical punch (probably the reason Ebright skipped it) since we don't have any "candidate" leak evidence either. Good job.
This stuff has been sampled extensively.
Or are you merely stating it's possible there's a bat cave no one's heard of that hasn't been sampled?
I don't think that's correct, for the simple reason that if those papers existed the (sigh) pro-leak folks would be linking them everywhere. Virology isn't exactly a trillion dollar field, we're not going out and sequencing every virus in every species. The Yunnan cave made news and was well-studied because someone stumbled on a SARS-related virus there, that says nothing about where that virus went later.
Those papers don't exist for the simple reason that "interesting" bats don't live there.
You might want to consider that while R H Ebright can be offensive and distateful, he has been banging this drum for 20 years and is generally very careful when he makes a factual statement.
As-if the only alternative to transported-to-labs was bat migration?
1,000 miles seems less ridiculous when it's animals in cages on trucks going to market — just a tiny part of the live animal trade.
(How many thousands of miles did Burmese Pythons travel to reach the Florida Everglades.)
That's not "spun", that's science. You're positing a COVID teapot that we have no evidence for. In a scientific context, it's not spin to omit stating "based on all available empirical evidence" after every assertion.
