Yes, it’s good to get info out quickly, especially in a pandemic. Yes, it’s very important that this kind of science is not stuck behind paywalls.

Many news reports about this article didn’t reference this Twitter thread. But likely if it were published in a major journal after review and with an accompanying editorial, the context might have gotten through better.
