Well, we learned a short time ago that hope is not a strategy.
Recall what happened when the good Dr. did make comments couple months ago about our supposed Wuhan Flu cure - he was quickly pounced upon by ambulance chasing lawyers parsing his words and claiming death and destruction ensued for their clients due to these comments.
I am willing to bet because of this - SRNE corporate council has said to Dr. Ji, "...zip it. No more personal comments as that cost "$x" thousands of dollars to mount a defense."
