Why was McDonald's chosen as the villain?
I think it is because McDonald's have a huge power that can be kind of scary. It is too popular in the US and is giving people bad influence for their health.
The message of the video
People are focusing on brands and companies are focusing on their profit too much. This would lead to a bad cycle of famous brands getting more and more power.
