Demonstrably false, even.
BP may be superficially similar to Batman now in terms of what he does, but BP has been fairly consistent in his portrayal since he showed up in the 60s. 60s Batman doesn't resemble BP much at all. More than a few of his early appearances in the late 60s and 70s were tied into civil rights and racial tension of the era, and marvel used him as a way to comment on it. Batman's alter ego was Bruce Wayne, millionaire playboy. BP spent his free time in the US teaching kids in the ghetto.
Again, BP has always been a very dark, conflicted character- but that conflict was between his responsibility as ruler of a foreign country, a celebrated superhero, and a second class citizen of the united states. Moon Knight is a Batman copy. BP was not.
And marvel's most visible and popular properties (captain America, Hulk, Spiderman, the Fantastic Four, the Xmen and related teams) are entirely original properties unrelated to DC.
