Personally, I don't see why one would hate SPA concept. I like it, because it enables to lower the traffic and make interactions... normal? And to use local computing when possible, instead of adding 2 and 2 over HTTP. When people hate SPAs they actually hate terminally overweight abominations that no one (i.e. google) keeps in check, and that's the reason they are like that. Why should on-page interaction be slow or cost one 20MB of downloads? No reason. replaceChild() uses the same tech as <a href>. SPA is not a synonym for "impotent incompetence 11/10". If humanity didn't invent SPAs, all these companies would just make half-a-minute loading .aspx-es instead. Because anything else they can not.
