That's the scope of the authorized investigatory use in the US, so unless you think the Trump Administration is simultaneously promoting and sabotaging it, I think it's the intended target:
“VEKLURY® (remdesivir) is authorized for use under an EUA only for the treatment of adult and pediatric patients hospitalized with suspected or laboratory-confirmed COVID-19, and for whom use of an intravenous (IV) agent is clinically appropriate. VEKLURY must be administered via IV infusion.”

The way I see it, hospitalized can mean: I have great insurance and I went into the hospital for treatment because I felt some symptoms. I was feeling 80% well when I went in, I was only there because the doctors wanted to be thorough and check my vitals overnight.
It can also mean: I don't have insurance and I waited until I was half past dead to go to the hospital because I have bad/no insurance. By the time I got to the hospital I couldn't even breath. I went straight to the ICU.
Both are 'hospitalized'. But I don't think the two examples represent the same reality. I'd imagine Remdesivir working very well on the first and not very well on the second due to viral load concerns mentioned in other parts of the commentary to this article.
