I got interested in 40K during 3rd ed, early 2000s, about the same time that the Tau turned up. They themselves the latest 'how do you do fellow kids' attempt to jump on a pop-cultural bandwagon that pissed off the old guard. I would guess that was when the satire included by bongs who took The Young Ones and 2000AD intravenously had been reined in, but before the crapsack grimdarkness started to give way to 'SpACe mArInES arE tHe GReAteSt hERoEs'.
The Tau was Games Workshop's attempt to make money off the anime crowd in the early 2000s, when anime such as Gundam and DBZ were taking the west by storm.
The Space Marine = Heroes thing is way too much like Warcraft. Reminds me too much of WoW Paladins who wore big shoulderpads, used hammers and holy magic, and were definitively good guys as opposed to the Space Marines of old who were self-deluded morons supporting a regime based on superstition:
"To me the background to 40K was always intended to be ironic. The fact that the Space Marines were lauded as heroes within Games Workshop always amused me, because they're brutal, but they're also completely self-deceiving. The whole idea of the Emperor is that you don't know whether he's alive or dead. The whole Imperium might be running on superstition. There's no guarantee that the Emperor is anything other than a corpse with a residual mental ability to direct spacecraft. It's got some parallels with religious beliefs and principles, and I think a lot of that got missed and overwritten."
Rick Priestley, Warhammer 40K author, in a December 2015 interview from Unplugged Games:
For decades, Warhammer has been one of the most enduring forces in all of gaming. In an unprecedented in-depth interview, we spoke to its co-creator Rick Priestley about its origins, development an…

I was long gone and had taken my autistic laser focus off GW by the time they released those childrens books. Holy shit. I get what you say about always needing to chase a new customer base, but that more than any other boneheaded decision by GW made me think they're starting to forget what their point even is. It's like Instagram changing to short videos only because Tiktok.
GW knows that the point is to just make money. And if one looks at their stock value, they're winning.
Don't they understand that the 'pew pew boom fuck you mom and dad' edgelordliness is what kids eat up?
Not according to their profit margins, it ain't. Kids love validation and fighting the good fight, and edgelordiness always takes a back seat to winning as the good guys and feeling good about it. Every franchise owner that made a fortune selling stuff to kids, from the owners of Pokemon to Star Wars, know that, and GW, in appealing to kids and going with straight-up, good-vs-evil stories, have done well for themselves financially:

Their profit margins have been rising since 2017, even as the fans got pissy over 8th Edition, the Primaris Marines, the lore changes with Marneus Calgar, and Warhammer Adventures being released. They made a killing in the Year of Our Lord, 2021. This despite pissing off the fans left and right. They made far more money pissing off the fans than they did when they were in lockstep with the fans. So if telling the fans to go FUCK THEMSELVES and appealing to kids will get them more money, that's what GW will do. The edgelord fans were only a means to an end, and that end was making money. If another group or demographic can rake in more cash for them, then appeasing them to get at their wallets will be GW's top priority.
