It looks to me like if there is one company here who has a “low information” customer that simply buys a product because they saw company sponsored propaganda, it is Samsung not Apple.
Furthermore, based on Apple’s comparatively low spend vs Samsung on selling costs, you could almost say that Apple products almost sell themselves. Word-of-mouth is free but the cost of earning this level of street cred is incalculable and it isn’t something you can buy with an advertising campaign.
