I’ve been trying to stay out of this pig wrestling match for a long time, but I should just make one point.
Framework financially supported Hyprland, whose crime was insufficiently aggressive moderation, rather than DHH, whose crime was not changing their middle of the road centrist politics when someone took a bulldozer to the overton window and pushed it away from him, and that formerly centrist position involves sending people who gained asylum by fleeing from Assad back to a country that no longer is ruled by Assad. They’re only mentioning DHH’s project, not paying for it.
As for why, I think it’s only because he uses it himself and thus finds it to be a cool project.
