Doesn't that imply that with Firefox OS, every app is second class? And if it doesn't, then why is the app "second class" when run on an iOS device? Phones running Firefox OS do have native apps running (e.g. the browser). Is Firefox OS doing the wrong thing by preventing users from installing native apps? If it's A-okay when Mozilla does it, the same should be true when Apple does it.
