See, this is what I hate about analogies. Instead of arguing the point, you end up arguing the analogy. Instead of clarifying, the analogy ends up obscuring.
In the original usage of the analogy, the 'chef' was the GM, and the 'eaters' were players. WotC is not a GM or a player. It's a company the publishes gaming media. You can't just repurpose an analogy and necessarily make a point. The analogy wasn't even necessarily perfect in the first place, and is likely to be even less perfect if you force it to refer to yet a third situation as if there was a one to and onto mapping between all three situations. There are lots of features of being a corporation that publishes gaming media for profit and being a DM that are different or exclusive to one or the other. They aren't perfectly comparable at all any more than gaming is perfectly comparable to eating a meal. If we want to keep extending the analogy past the breaking point, then WotC is analogous to a corporation that is preparing to launch a new line of casual dining restuarants, and I am a franchise owner/chef that has to decide whether to invest my money in opening a new restaurant. But really, by this point the analogy isn't helping understanding; it's hindering it.
