Haskeller here. I don't want to use Elm myself, but I think this is really unhelpful. Elm is bringing new people to static functional programming environments that emphasize immutability, purity, algebraic data types, pattern matching and a lot of other great features. Yes, writing serialization instances by hand over and over is a huge drag, and like, there is a better way. But the better way doesn't need to include condescending mockery.
