I think neor (
https://news.ycombinator.com/item?id=9776826)'s point is the intended impact on
developers, not on
users. I believe that the contention is that Apple hopes to coerce developers—or, rather, content providers—into taking down public-facing web portals that are out of Apple's control, where their ad revenue will plummet, and creating instead an app that is to some extent under Apple's control, because that will become the only effective way to get ad revenue.
Your choice as a user will then go away; there are already some, though fortunately not yet many, sites that
must be accessed through apps (for example, my bank accepts deposits only through their app).
(I'm not endorsing this point of view myself, although it sounds more than a bit plausible to me; it's just, I think, what was being said.)
