For many people, it's a Satanic symbol and thus they want nothing at all to do with it.
It's clearly not a satanic pentagram but apparently some sort of authors inside joke. Sure, it's based on it, but as you can see there's more elements added https://imgur.com/PxKw5Yw
Throughout history five pointed star or its variations have been used in various cultures, ideologies etc. so I don't see it as a "deal breaker".
That's pretty hilarious, then again I'm not the masses. Still awesome though.
Looks like a ritual to protect against nasal demons.
