I think researching how these viruses can become dangerous to humans is the main goal in research like this. That a natural mutation would look similar speaks for their expertise and isn't necessarily controversial. It should be controversial if lax security measures would permit viruses to spread from a lab. We have absolutely no evidence of this to my knowledge and should be careful with accusations.
