I respectfully, but strongly disagree.

From the article you cited:

Direct person-to-person transmission is the primary means of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). It is thought to occur through close-range contact, mainly via respiratory droplets; virus released in the respiratory secretions when a person with infection coughs, sneezes, or talks can infect another person if it makes direct contact with the mucous membranes; infection might also occur if a person's hands are contaminated by droplets or by touching contaminated surfaces and then they touch their eyes, nose, or mouth. Droplets typically do not travel more than six feet (about two meters).

SARS-CoV-2 can also be transmitted through the airborne route (through inhalation of particles smaller than droplets that remain in the air over time and distance), but the extent to which this occurs under natural conditions and how much this mode of transmission has contributed to the pandemic are controversial [15-18]. One letter to the editor described a study in which SARS-CoV-2 grown in tissue culture remained viable in experimentally generated aerosols for at least three hours

The science is, as noted less clear on the transmission from aerosols (as opposed to respiratory droplets) and fomites.

Truthfully, I am extremely disappointed that any would seek to cast doubt on the risk of transmission from respiratory droplets.
