That said, I don't mind that these "research" organizations exist. Only bothers me when they put the general public at risk (or attempt to) for their own gain.
AMD isn't going to crash and burn over these flaws anymore than Intel (at 5 year high) did.
So, AMD has vastly more incentive to be accurate than short sellers.
AMDs incentive, like any corporation, is to maximise shareholder value. Same as any tiny little security research firm. If a research firm can maximise their profit buy discovering vulnerabilities and shorting stock before disclosing them, is that any ethically worse than a chip company rushing out flawed hardware with big flashy marketing bullet points claiming how secure they are?
(I'm not saying short-selling chip vendor stocks on the back of vulnerabilities is a way I'd choose to make a living, but surveillance capitalism doesn't seem an "ethically better" industry to work in either...)
As to ethics that's mostly irrelevant to this discussion. Both sides could have ethical behavior, I am simply pointing out which side has the larger incentives to exaggerate. After all the stock could drop and a short seller could still lose money. They need the stock to drop a lot even over a minor issue.
Short sellers want the opposite. So they both present their best cases and let the public decide, much like how lawyers will defend their own clients to the last breath regardless of the amount of evidence against them
Although I enjoy reading grandparent's counterpoint
It's sad to see people arguing for a return to those norms, especially since the rejection of them correlates with a renaissance in our understanding how to secure software.
It's not like AMD set their chip prices based on "ethics" or "duty to the public". As "the public" I'd prefer a Ryzen 1900X to sell for $150 rather than $500 - It's just a bunch of sand after all (plus some intellectual effort). I don't think AMD get to choose their pricing model but then complain about how security companies price/sell their intellectual work...
I'd say that the intent makes this qualitatively different to what I'd consider legitimate disclosure.
It's not like their marketing copy makes accurate claims like:
"We're reasonably sure our Firmware Trusted Platform Module is trustworthy, but we ran out of time to pentest it properly before we shipped it."
or
"Ryzen features Probably-Secure Encrypted Virtualization! Our interns couldn't break it in a afternoon of trying! The data looks random enough to us..."
How much does "the intent" of their marketing copy and claims come into play?
Where do you see anyone arguing for that? Or is it just a strawman? What I see is not people arguing against disclosure but people arguing for disclosure with an embargo longer than a day. You're going to have a hard time proving that one day is a norm, or that it correlates with a renaissance in securing software. Your response looks much more like circling the wagons when a member of your tribe is criticized.
A good way for companies to prevent this is to have a generous bug bounty program. Money is still transferred from the shareholders to the researchers, but then the company can impose conditions like delaying public disclosure for a reasonable time to prepare a fix.
Which they should be if the alternative is a much larger loss to the company's share value. The shareholders come out ahead to pay five million on a bug bounty if the alternative is to lose a billion dollars in market cap.

Do you think there's _any_ chance AMD would have offered these guys money in the sort of magnitude they stand to gain short selling AMD?
I'm pretty sure if they'd asked AMD would have responded with a blackmail lawsuit instantly.
