The comrades in the hospital said: blood donation without compensation is a scam?

Blood panic occurs in hospitals, and critically ill patients have no blood available, which is the most common thing. I have read this post, and I dare say that I have spent more time as a doctor of medicine than my online friends. A real doctor doesn't have to emphasize his identity so much, you can see it between the lines. I'm afraid I'm not selling blood. I'm afraid that everyone will donate blood for free and I have no business to do.
