Its what tobi also said its pretty much a given that he got hashi's dna. Meteors isnt madara's tech are u not reading the manga. He did not disagree to kabuto's claims
madara clearly says the meteor is his own power, he uses it from his rinnegan similar to how nagato used that same tech on a smaller scale. its his power as he clearly says it here

Immortality is something he gains from edo like everyone else its gonna be there whether he likes it or not. so that is such a bs point you're trying pull its the same with mu and every other edo. and it didnt matter for the most part he would obviously battle differently ad be more serious if he didnt have it.
Mokuton is actually something he completely did get from kabuto and its a great power but not most of his power by any means.
He has the rinnegan+ ems + he is enhanced by hashi's dna but obviously cant use mokuton. Which is in itself a great power and only tobi so far can beat that and that is from his also "borrowed" powers.
he can still use paths like preta and deva path powers and more with the rinnegan, still has perfect sussano which is incredibly strong and the rest of his ems abilities which is the majority of his arsenal not just mokuton. So ur claim is utterly stupid since most of his powers are actually his own but no doubt mokuton made him considerably stronger but even without it he can do the same to kages as he is doing now
Stop trying to underrate madara even without mokuton he can own almost any ninja and you're clearly trying to take away powers even from the rinnegan such as his meteors its clear as day you're hating and trying to make him seem a lot weaker than he is
