You pretend as if this is a totally alien concept, while you yourself use HN in a browser. Literally everyone uses a browser. The whole point of the post is that you don't have to ask your users to do anything other than click on a URL. It is obnoxious to act like you can't understand this.
And with a native app you don't have to ask your users to do anything than double click the App (or tap the icon).
More importantly: you don't have to ask your users to hoover up all their data, it is already there in your server!
Not to mention trying to convince them to use the latest version with all the (mis)features it might have: they have no choice!
