The author does very little to support his claims. The Boston Globe page also has lot of scripts to support advertising and the advertising itself. As well, entirely different engineering teams and probably cultures. There's not even any research into The Boston Globe's use of progressive JS; it makes ZERO sense why the two homepages could not have the same JS footprint, with The Boston Globe continuing to work and Bustle continuing to not work, while JS is disabled.
I'm all for not supporting progressive JS; Bustle is certainly within their right to not work without JS; the author is just caught in a confirmation-bias bubble. His conclusions don't make sense; our intuitions are right; it doesn't take [much] more JS to progressively enhance a site.
