I'm using de jure to contrast the de facto; I think frameworks are the "next big thing" before they're even fact. That Javascript Guy comes up to you, asks you what you're using, and then berates you for not using Hot New Thing, de jure-ing you into using it, or at least feeling bad for not using it.

Part of the way I've resisted being sucked into the JS vortex over the past few years is that I thoroughly reject the authoritative claims that I should be using X or Y, on the grounds that I don't particularly respect the technical judgment of the people making those claims. (And check that last clause carefully; all the Next Big Things are generally engineered pretty well, it's the advocates berating you for not keeping up to date that I'm dissing.)
