An idea for an app I came up with for a class once was one that let you scan a barcode of a product in like Walmart and get what parent company owns it, like how Nestle doesn’t like to put their name on companies they bought (or not in big text anyways).
So if you want to avoid Coca Cola you could scan it and see who it’s owned by and if that company matches one of the ones you have blacklisted
Fun fact, ‘peace tea’ is owned by coca cola
why do you hate .world?
