What, do you sincerely believe Palantir is pulling the strings behind Ladybird? What is the accusation here? Everybody can be "connected" in some way or another, but it's meaningless.
4 steps is not so bad
I understand that not everybody cares about this sort of thing, believing that politics of developers should be irrelevant; I'm personally not going to go around ringing the shame bell at people who use Ladybird (or Rails. But Kling loudly shouting "I support the free speech rights of fascists but get away from me with that DEI shit" doesn't give me warm fuzzies about using Ladybird, either. It's a lot easier to let politics of developers be irrelevant if the developers aren't out there energetically sharing them.
