I'm consistently amazed by HN's ability to take the most meaningless, inconsequential part of an article (the scroll behavior, the whitespace, the usage of the word "bricked"), and nitpick it to hell and back instead of actually discussing the article.
Apple apps can only be developed on Apple computers and if you pay a fee to Apple for the privilege. And they own the app store. There's lock in and then there's complete vertical integration.
Bravo.
