Copyright is like patent.
Some today want to find a COVID-19 vaccine, to patent and sell. Those who can afford the price, live.
In 1953, Jonas Salk invented a vaccine for polio.He did not patent it but gave it to the world. Polio was destroyed.
To sell a cure means that disease must live, or the investment is worthless. Health for profit depends on disease to stay in business. Education for profit depends on ignorance.
We eradicate ignorance by making knowledge free. #LiDA103
