Lolno. People buy the minis because they look cool and like collecting them or painting them or what not. Not because of lore. The sets that sell well are the front and center easy to understand sets that are also the subject of games, by an overwhelming majority, Space Marines, the thing you need no lore to understand because they are conceptually ubiquitous.
Most people who are buying minis aren't deep diving into books to figure out which has the most interesting backstory, they buy the ones they like the aesthetics of and thing are cool.
You don't realize it, but this is evidence of exactly how wrong you are. The reason that lore channels get lots of views isn't because the lore matters and is what people care about--it's the exact opposite, they get lots of views because people get into a thing not giving a shit about the lore and then don't care enough about the lore to go read a novel or deep dive into wiki articles themselves and would rather speedwatch a youtube video that summarizes lore points so that they know the basics and don't have to invest any significant amount of time in it.The lore channels on youtube have millions of views on their videos... while the tabletop/figurine centric ones are lucky if they get over half a mil.
Warhammer IS known for its lore... you can deny that all you want, but its definitely not false.
The people who are racking up views on Nobbel87's channel (or god forbid Pyromancer's), are not the people who are really into Warcraft lore and play the games for lore and read all the books--because they already know all that shit and don't need a bullet point list of things they're already aware of. The people watching those channels are people who spam click through quests, are barely aware that WoW has books, and then don't understand what is going on and want someone to explain it in an easy and quick way. Someone who knows warcraft doesn't need "the entire story of warcraft in 40 minutes", the average player who doesn't really care does.
The exact same is true of both warhammer and 40k. 95% of people who clicked on Astartes, or who buy Virmintide, Dawn of War or Space Marine, or have ever used the phrase "blood for the blood god" do not know (or give a shit about knowing) the lore of Warhammer or 40k. They know that it is a thin,g and they probably know that it involves some analog game, or that it has video games and they might know that there are some books for it. People who are into 40k lore are a tiny, specialized niche, even amongst people that fully know what 40k is and have played games or have some physical figures.
