You're right, when we share information, there is a risk that a country could use it to gain an economic advantage. However, that carries far less risk than threats to our public safety and national security. Five years ago, China or scientists in China might have used the information for an economic advantage. However, the consequences of that are not really serious compared to using a virus as a weapon or as a threat to the global population, which is a completely different ball game. As I already explained, I find it extremely unfortunate that it's now impossible to cooperate with a billion people on viruses.
So, they are two very different things.
