John Gruber believes so:
When it comes to media, what strikes many as The Daily’s cardinal sin is eschewing the open Web for the closed garden of a subscriber-only iOS app. The idea being that you can’t win without a web-first strategy. But that’s what “everyone” said about social networks too — until Instagram came along and became a sensation with an iPhone-only strategy.
Felix Salmon is skeptical:
[W]e’re going to see universal journalism, which can be accessed — and possibly edited — in different ways on different devices. It might be free on the web, for instance, while costing a couple of bucks in the form of a simple iOS app. Maybe it will only be available on iOS, but for business-model reasons, not because it couldn’t work on the web. Or maybe, as in the case of Matter, it will be available in any format you like, for a single flat price.
