Spoiled food makes no sense indeed. However, what this guy does makes definitely business sense.
People do not care about the truth.
+ Fake news goes viral.
+ Medium tells people that the ones who passed away still love and talk to them.
+ Religion in general.
+ Advertisements about medicines with fake doctors.
+ Advertisements in general.
+ Gossip.
+ Sensationalized scientific breakthroughs.
And then there is a lot not true, but it is at least within a context clear that it is not true, like fairy tales and literature. All the other examples are however disinformation and people doing business using it.
