That's my point. This doesn't sound at all far fetched if you've spent time with people recovering from psychosis with visual hallucinations.
I'm normally a very skeptical person, and while I both agree claims require evidence. I don't find the comment thread from before very compelling evidence.
Fake or not, I do believe that an ad with the text from the troll image would show up on a smart fridge, I don't trust Samsung to tell the truth^1, and importantly the minimal description from the linked post describes an experience similar to one I've seen before working with a patient. (But from a print ad.)
Even if this exac is fiction, this kinda stuff actually happens. Perhaps I'm wrong, to believe it's plausible, but dismissing it outright is a mistake. You don't want to acknowledge hallucinations are real, but more important than that, you don't want to tell someone that they're lying without positive proof.
edit ^1: I read that exactly prior to reading your reply, and yes I do agree that explanation seems to be correct; that wasn't what I was basing my take on. i.e. true or not it's less important to my original objection. Or I find it plausible than even a small advert would result in the same event.
I trust them more than some reddit post. Samsung has at least some incentive to tell the truth (they don't want to piss off consumers). What's the penalty for lying on Reddit?
