niche artist (nickname 'antireal') makes a bunch of posters and logos in the 'vectorheart' style back in 2017 and posts them on his twitter
Bungie artists know about this antireal guy and start following him on twitter
Bungie artists like the style and (presumably) save a bunch of the guy's artworks for reference materials
something happens at Bungie and a bunch of antireal's art pieces (or segments of them) end up in game on Marathon assets and in Marathon marketing materials
people claiming to be Bungie artists/employees posted in earlier threads saying the stuff wasn't ever supposed to get in game, but some kind of mixup happened during the layoffs and the reference files got mixed in with 'ok to use in game, we made it ourselves' files
The stuff about 'Bungie stole the whole look of the game!' is just the usual internet hyperbole.
Hanlon's Razor, anon. It's incompetence and organizational dysfunction, two things nu-Bungie is infamous for. I agree that the higher ups deserve a lot of blame, but for different reasons.
Yes, and I laugh about it every time I do
