My guess is that it's a similar social phenomenon to flat-earthers, qanon, etc, in that a group of like-minded people form and customs emerge in which making ever-more outlandish claims are taken as stronger commitment signal to the group. I was reading last week about an 'audiophile ssd' product and I browsed an audiofile forum thread[0], expecting to have a chuckle at users ridiculing it but there's actually 6 pages of people praising it and finding new adjectives to describe the sound it produces. The most popular posts [1] also detail other absurd things they have done to produce a better sound- "I can opt to convert a FLAC to WAV format and play that from RAM, this somehow lowers the perceived noise flow and makes music sound more organic and detailed"
