Boo hoo. Researchers tell the world for free exactly how to implement their state-of-the-art work (which probably cost north of $1M to develop) and promise to release code, and we're indignant because they didn't do it quite fast enough for us.
(2) I'm not aware of this promise you're speaking of... my understanding is that authors of papers are under no obligation to produce any implementation, let alone usable, documented implementations.
The work was done at FAIR (Facebook), so that's not applicable here.

Look at the paper [1], it's the last sentence of the abstract: "Code will be made available."
