QAnon is a dynamic LARP. There is no conspiracy that they can't absorb. The anonymity of the authors is a feature, but it also means there is no person who can authoritatively deny that the WayFair conspiracy theory was not related to the core "deep state" one.
Honestly, my analysis of the Wayfair storage bin incident was that it was probably a LARPer (QAnon, 4Channer, Russian/Chinese troll, whatever) who had access to the WayFair vendor admin panel and realized that QAnon followers would eat it up.
