When giving out numbers scientifically, it's important to be precise, or have the uncertainty known. In that case, 96% is widely different than 70%. As Andy Slavitt says in his April 22 podcast, when someone claims to know something too precisely in regards to this pandemic, and they don't say "we don't know" enough, run the other direction.

You also want to have someone doing a scientific study to be as unbiased as possible. As I understand it, (most of?) his family is immunocompromised. This doesn't mean he shouldn't do it, nor that what he's doing is not saving millions of lives, but it's a little easier to question the "salesmanship" aspect of it when he hasn't spent a lot of time in the field.
