dishwashing liquid

yesterday I saw this huge advertisement for dishwashing liquid on the side of the road and I wondered why the company might be worried about not selling enough dishwashing liquid as it is almost the only thing you can buy in the supermarket.
so two possible explanations arouse in my head:

1. the ad was sponsored by the government because they want us to live on dishwashing liquid as possible and when everybody has enough for the next few decades and the shelves will be empty there will be food again.
2. the company has to sell as much dishwashing liquid as possible to be able to sell food at the low prices, the government has set and still be able to pay for the fuel that drive their generators.
