They've had enough. The pigs go on strike. They are protesting the terrible living conditions and demanding welfare orientated animal husbandry, calling out Lidl and Aldi for supporting factory farming by offering cheap meat products and last but not least pointing out damages to the environment caused by factory farming. Message can be adjusted. I can see this in many formats, even street guerrilla campaigns with large marching pigs in cardboard format.
