The smugness is when you classify a bunch of other people as annoying as if they are incapable of making their own technical trade-offs. "Wake up, sheeple!"
I use Redux on just about every React project because none of my projects are toy projects. And I'm not just doing it to annoy OP.
I like React's ethos of avoiding complexity until you need it, but these smug attitudes are starting to get really tiresome.
