I think it's best to ignore this kind of user feedback and focus on the users who really want the service or product and are willing download an app if necessary or use the web version if necessary. Popular opinions on apps/web and desktop/mobile change every few years. I remember when Facebook became deeply unpopular and was afraid of going under because they didn't manage to provide a native app.

Because of the walled gardens, duplication of efforts, and waste of resources I'd personally favor if apps died out but that is never going to happen because they always have better platform integration.
