"I've seen on Reddit, Twitter etc that many people are bending my words to state that the XIM is now 'OP'. Nope. Not at all what I've said. Here's what I've said in the past:
"In Destiny's sandbox, because of how the aim assist has functioned, a controller with aim assist is on-par with a mouse with aim assist via the XIM. When you leave Destiny, things change. But we're talking about Destiny, aren't we?"
In a further statement to PC Gamer, Dr Lupo points out "the XIM still involves translation, which means it will never be as precise as a native mouse." He also acknowledges that the existence of any aim assist will give salty players a cop-out excuse for losing, inviting toxicity in the community.
