OP didn't like the notion that
40k is for kids but I quite frankly don't see the problem. Kids are smart, my twiglight struggle box says 14+ and it's
imo a great game, most
FFG games are 12+ afair and I like quite a few. Not to mention you ussualy start playing chess few good years before boardgames and wargames and it does not insult chess in any way or take away from the king of games aura it has.
GW as every other gaming company obviously has to target kids/ teens as non gaming 30 years old are pretty immune to people trying to sell them a 50$ plastic doll (most people who do not knowing wargaming whom I ask about what they think my Hive Tyrant price is say something around 3$ - 10$ equivalent), the gaming kid is a future gaming adult. That does not make
40k a kiddie game by itself. Bryan Ansell said in an ancient times that the target demographic for Warhammer books and games is "intelligent 18 years old" but that for me sounds like a compliment for a game, not an insult.
And here's Rick Priestley about target audience:
"
The audience for Warhammer grew up with the first three versions"

Sure that's ancient quote too but I'm quite sure
GW of today isn't just ignoring the huge adult player base and making the game for kids.
Also
OP if you read, the idea that Warhammer
40K 6th edition is not a competitive game and that
40k never was is senseless.
GW might pretend it is not as an additional excuse to stay lazy about balance but it is competitive by nature since 2nd edition, and it was stated so in 5th edition rulebook. Here's Priestley again:
WHFB
"
Yes they certainly were! A lot of the complexity of 3rd was inspired by standard historical wargames rules such as WRG Ancients. That was a tournament rule set really – with a great deal of fiddly movement post combat as I recall. "
WHFB and
40K
"
By then both games had acquired a character and a commercial role that took precedence – so it was more a question of making sure they worked well within very narrow and specific commercial boundaries. I think that ‘head-to-head’, point value driven, army list moderated, competitive or tournament style game was just the ‘commercial’ side."
Casual beer and pretzels games are quick small and easy games not wargames with behemots of rulebooks.
