I think that's what the grandparent is referring to: "physical contact" as opposed to "in aerosols". I don't think they meant actual physical contact with infected people.

What makes you think that isn’t accurate?

Yes - that's what I mean. Virus gets onto hands via touching objects & surfaces, and from there to face.

Also (to be fair) if you want to increase your chances of getting accurate info you probably need to go to more credentialled sources than some random guy reporting on an unnamed podcast in an HN comment ;)
