He said for production. Meta hasnt produced fully baked production-ready products from their research for public consumption.

That is the point of the post and Yann's reaction as a Meta employee reeks pettiness.

He first told everyone that ChatGPT is not revolutionary at all. May be a fair point. That's debatable. Then proceeds to post a chart about Meta and Google big tech as producers of research that others just consume. Then when asked about what research has they put into production, he claims that it's not that we CANT, it's that we WONT. Then proceeds to bring out what happened to Meta's first trial to do it -- Galactica that embarassingly failed. So all in all, he seems to be criticizing why these companies just consume established knowledge by sprinkling something on top from what they have published.

I'd honestly expect Google and META to be quite cautious now on how they publish stuff since OpenAI's moves build on top of the established research that they do.

No one also said they are publishing junk. That's a strawman. The point is that he's being overly critical to startups like OpenAI who consumes established knowledge that they voluntarily opened to the public and has started to profit from it, while they have failed to produce something profitable or usable for public consumption.
