...but you can. And, open your facebook Marketplace (I know, I know) and just type any food you like. You can buy it there, made by people like you. Risky, maybe, but you can.

That's the point.

It obviously depends on local laws, but it's very commonly illegal to sell prepared food without a license/permit. You might not get caught selling food on FB Marketplace, but that doesn't make it any less allowed.

I agree with the author regarding Apple's walled-garden app distribution, but the analogy just doesn't work here.
