It's probably illegal too, as in many jurisdiction the public, or at least a health/food regulatory body should know the process and ingredients.
Take into account allergens, and on top of a matter of public knowledge and health, it can also be a matter of life and death.
It's like saying "Linux uses C" and now you instantly can copy Linux =)
It does however play a hugely important role in a recipe, in a way than the choice of language doesn't play in a program (especially considering turing completeness). So the analogy is broken.
Besides nobody made the point that list of ingredients makes a recipe.
Just that it's important to know the list of ingredients for a food you're gonna eat, and that it's even illegal to not disclose them (either to the public or a regulatory body) if you sell food.
Apologies if the parent comment was edited after you wrote yours but a "process and ingredients" does a recipe make.
If you actually care about this, stop alienating potential allies, and ideally start making arguments to support your case instead of telling people to RTFM (which in this case is even worse because "the manual" isn't as much of an authoritative mic drop as you seem to think it is).
> We campaign for these freedoms because everyone deserves them. With these freedoms, the users (both individually and collectively) control the program and what it does for them. When users don't control the program, we call it a “nonfree” or “proprietary” program. The nonfree program controls the users, and the developer controls the program; this makes the program an instrument of unjust power.
It seems safe to say the author thinks that one creating "an instrument of unjust power" for oneself is unethical. Though, perhaps if the commenter in question pulled that quote out of the article, it could have helped their point.
