As a top level comment, it is valuable to point out that many executions of SPAs are lack lustre and will not deliver a superior user experience. If it was a top level comment and didn't lead with contradiction of the prior comment, I would have affirmed and probably not have posted anything. That is why I started by telling the commenter that I believed he actually produced better implementations, because he has a point but not a point that is meaningful to back up his disagreement. The point of the comment chain in question is that a given UI has a need for a given amount of state. That is the point that was "[believed] false" and the point I was reiterating. User feedback is not useful at all for determining whether SPA's will require more state than multiple "plain HTML form"s. Moreover, the key assertion of the article is that this is necessarily the case, a point which is asserted without evidence and used as the foundation of the entire article. If you remove that assertion, the whole article collapses.
