The headline is a little misleading: the article isn't about not using web technologies in favour of native apps - Instagram, for example, uses HTML5 for most of it's UI (you used to be able to see the error pages) and has great UX - but rather a call to stop making 'native app like web sites'.
> Our working assumption has been that all web sites should be app-like, and therefore tooled up to the hilt.
I don't think that's true. Some people create horrible scroll jacking functionality for whatever reason - maybe they thought it was more 'native app like', maybe they just thought it was clever. But many other web developers already consider that bad perf is bad perf and aren't willing to put up with it.
