Something that just came to my mind, if he is so unhappy with the current course of 40k, why not make videos about something like a old-styled DIY 40k army consisting of 3D prints or modified models from other toy companies?
He's never done anything hobby or gameplay related in the decade he's been at this shit. I mentioned it in another post, but most 40k channels(including ones he was calling out the other day for some reason) that aren't hobby channels have still posted or at least discuss some hobby related content on occasion.
But sperging at the camera is easier so that he can get youtube shekels for no other reason than him having the same political takes as his viewers.
You mean his dwindling viewers?
I'd be willing to bet he's an autist who got fixated on 40k ages ago, played some of the video games(that's how his channel got it's start... kind of, so he's not even a videogame channel) did some deep dives on the lore for WHFB and 40k, and that's about it. He then spent the last half decade complaining about GW, occasionally discussing british politics(he's not even british, he's norwegian or something and still lives there), doesn't even do more than glance at "newer"(so shit that's almost a decade old now) lore, and has been panicking about his channel dying since. The only legit complaint he has(and I'm honestly not entirely sure it's even true at this point) is that GW "forced" him to remove "Warhammer" from his channel name and now he's just Arch, and how that was going to screw him but he clearly still pops up on occasion even when people aren't looking for his videos.
I wouldn't call him a tourist, but he's definitely just a secondary who never engaged with the other 2/3 of the shit GW does, and doesn't even read lore at this point either while trying to run a lore channel.
edit:
That's the oldest video still on his channel from March 2015. You can hear his norwegian accent, he doesn't RRRRRRRoll his RRRRRRRs ridiculously(you can still hear it around 1:45 when he's talking about the khemrrrian kingdoms but it's not as ridiculous as it is today), no smuckling, no bitching about politics(and politics were definitely an issue at the time thanks to gamergate, sarkeesian, etc.)
This is another video from January 2016, so not even a year later. You can hear he's trying to hide his accent better, has a slightly better mic but now he's stressing S sounds, still no smuckling, no ridiculous rolling of Rs, no politics, etc.
July 2019, now he's smuckling. Has his modern accent, still isn't rolling his Rs ridiculously, and it's toward the start of his bitching about politics, game devs, GW, etc. still a year or two before starting his archcast channel.
