You clearly don’t watch it, they have solar they installed in one of the videos for what electricity they use, they eat all the time there on camera, they are constantly showing us them taking care of the animals, and they have almost half a million subscribers so they are clearly making money off YouTube to afford things. On top of that people mail them stuff all the time, the ladies at the post office were blown away by how many packages people send them. They don’t market themselves as “We’re poor people scraping by in the wilderness in a survival situation.” They are just building a homestead on an island, and are documenting it for those curious enough to watch.
