I looked up the person (Li-Meng Yan)[1], the paper[2], and the Fox News Interview[3] where Tucker Carlson "gleefully flogged" the bioweapon theory that this article references as being part of Steve Bannon's faction of right wing cranks.
In the paper Yan describes "an unrestricted bioweapon" like so -
Although it is not easy for the public to accept SARS-CoV-2 as a bioweapon due to its relatively low lethality, this virus indeed meets the criteria of a bioweapon as described by Dr. Ruifu Yang. Aside from his appointment in the AMMS, Dr. Yang is also a key member of China’s National and Military Bioterrorism Response Consultant Group and had participated in the investigation of the Iraqi bioweapon program as a member of the United Nations Special Commission (UNSCOM) in 1998. In 2005, Dr. Yang specified the criteria for a pathogen to qualify as a bioweapon:
1. It is significantly virulent and can cause large scale casualty.
2. It is highly contagious and transmits easily, often through respiratory routesin the form of aerosols. The most dangerous scenario would be that it allows human-to-human transmission.
3. It is relatively resistant to environmental changes, can sustain transportation, and is capable of supporting targeted release.

I don't know that's the exact definition I'd give for "bioweapon" but it seems plausible, from a somewhat authoritative source, and fits covid. In other parts of the paper Yan addresses what she calls the "cover-up" of the lab origins of covid-19 and she points to elements of the cover-up that predate the outbreak and concludes "the unleashing of the virus must be a planned execution rather than accident."
On the Tucker Carlson interview the host listens to Yan's points and invites an expert on. The expert seems to basically ignore Yan's more exotic claims (i.e. that it was an intentional attack) and summarizes the situation at 3:39 as "We don't know" and gives two possible explanations as "Zoonotic transfer" or "Accidental lab release" and leans towards the latter. That seems exactly right to me.
I don't follow the "cover-up" part of Yan's argument (though I will read more about it) so I can't comment on her conclusion that it was an intentional attack. That's certainly not what other people I've read seem to think. The "bioweapon" definition seems a bit like an exaggeration or a technicality, if only because "bioweapon" conjures the idea of much more severe and lethal and viruses.
My point is that the right wing cranks actually come out looking pretty good on this topic - as far as I can tell. They immediately questioned the natural origins and advanced credible arguments for lab leak which are gaining support and evidence. I think it's wrong for this article and others to start out, and dedicate space in the opening of their argument, to try and balance things by saying, essentially, "Yes, maybe the experts were wrong here, but so were the crazy right-wing people." The people who are really and clearly wrong here are the mainstream media outlets who blindly trusted the authorities that told them this couldn't be a lab leak. Tucker Carlson talked to Yan, who may not really be a virus-expert (her degree seems to be in Ophthalmology) and may be over-zealous in her anti-China stance (e.g. concluding it was an intentional attack on what might not be very good evidence) but Tucker Carlson and his show explicitly call out the two main theories as what I believe they still are - i.e. zoonotic transfer and lab leak.

Even a broken clock is right twice a day. Worse is that said broken clock embraced thoroughly xenophobic language that almost certainly led to a rise in anti-asian violence. It unfortunately made it easier for the public to discount these arguments because it was impossible to tell whether they were being made in good faith, not to mention that these arguments were often made out of a (justified) distrust of the Chinese government rather than an objective understanding of the known facts.
