I get the aspect of "shiny things are shiny and I like shiny things so I buy them" but the things that piss me off, like actually genuienly make me mad at the whole thing are actual scams like "audio tuned" ethernet switches or "designed for music" SSDs. These are actual products that sell for a lot of money, and they physically cannot make any difference to the audio played from/through them. It's worse than snake oil.
