"It was not the same strain responsible for the current epidemic....
"...Their study suggests that in certain circumstances, one particular strain of Ebola with no documented evidence of infecting humans but is deadly to other primates, might be transmitted airborne from pigs to macaques."
The current pandemic is most likely Ebola Zaire. The first 2 of your links state the Canadian study was Ebola Zaire; the 3rd article doesn't state which strain was used in the study. So it is the same strain, and the study suggests that in certain circumstances the Ebola Zaire strain might be transmitted airborne from pigs to macaques.
That said, I prefer a softer word to "prove" with such a limited study as well. It appears to have been aerosolized, but it's also possible that contaminated water was splashed into the macaque pen.
