Where the case is made that fandoms are composed not of people laser-focused on a single mono-topic, but who are *generally* nerdy, conversant in a range of fandoms, some related, some not, but all somewhat similar in having canon and lore and the like. The point being that when franchises and IPs are taken over by people who are *not* nerdy, they cannot relate to the fans, and end up making a mess of the product. They have fundamentally different worldviews.
