Matt's wrong about why he's seeing the adversarial stuff mostly on Twitter. It's because there, people don't experience the rampantly over-the-top hypersensitive censorship that occurs when they express Gutenberg-critical views, even mild and polite ones, on the Wordpress-controlled media (e.g. plugin reviews).

So what he's seeing on Twitter is closer to what people really think. And what people think is that Gutenberg is a big mistake. It's a breathtakingly bad idea, astonishingly poorly implemented. But Matt likes it, so I guess that's all that matters.
