A number of little things that are totally not proof of anything, hence calling it a tinfoil hat theory. It did seem like they were setting up to remove or sideline Slaanesh in 40k at the same time though with the Ynnari plot before they cancelled all their books suddenly.

That's not just some random spiky symbol, that's malekith's crown

And malekith is weird because they had another early 'error' where someone copy pasted something into a book that called him a chaos god, and because despite being one of the characters that got an artwork in the very first rulebook for aos, we still haven't seen him or his faction after 10 years, pointing to some heavy reshuffling behind the scenes
