Further to that, there are plenty of people who can't really articulate what a web browser actually is or how a website differs from an app. It's not clear to me whether these users would be more accepting of a PWA or if they would be even further confused by them, particularly if they have to be left to find the app on the web first in order to "install" it, even more so if they've never bothered to look at what all those buttons in their web browser actually do.
