Neither me, but you and I have agency and free will. This model has neither of those things.
I think the crucial question is does this 'model' have the capacity to develop those things. If it does, that creates a serious problem for continuing research along these lines. If not, then I don't really see them problem - in that case I would compare this to growing and running test on kidney or liver.
Morality we know is encoded in human brains anyway. We may not like it, but that doesn't mean it's not moral from alien's POV. And yes, in such case, tough luck for us.
If there were actually a reasonable case for why fuqismatk or missildrigg were necessary rather than arbitrary criteria for the thing to be bad, they might have a point. If I found out an alien had been doing something to me that is imperceptible and harmless from my perspective because I lack fuqismatk or missildrigg, I wouldn't feel any ill will toward that alien.
There's a difference between prodding your brain or prodding a brain modeled after your brain, which doesn't have a way to sense things prodding it.
let me help you take your example further:
"These humans, they might have agency and free will, but they don't have fuqismatk and missildrigg, so us gakimiking and monikiking their brain should be ok."
