The argument that it’d help detect risk doesn’t seem very good, we know these researchers published work on similar viruses and it doesn’t seem to have caused anything to change and increase safety.
The argument that it could contribute to vaccine research doesn’t seem to have held up either, AFAIK there’s no link between such research and the Covid-19 vaccines we now have.
I’m sure there are other arguments for the research, and I’m sure it won’t stop regardless of what people want given how the article says Obama’s moratorium was treated and the obvious military applications. But it seems that the experience of Covid-19 does drastically alter the risk/benefit calculation of that research given it seems to have had no benefit in practice.
