Your source is basically making the argument that any virus contained in saliva or mucous will be contagious by sneezing. Yet the argument that Ebola is not contagious in such a manner isn’t theoretical but observational.
My source is the CDC.
When an infection does occur in humans, the virus can be spread in several ways to others. Ebola is spread through direct contact (through broken skin or mucous membranes) with blood or body fluids (including but not limited to urine, saliva, feces, vomit, and semen) of a person who is sick with Ebola
