Tbh, I think this is just a marketing pitch. They can't exactly admit that the rewrite resulted in cut companion content and messed up main plot. Because the way the tadpoles worked with Daisy in the EA was different, and there are still leftover lines from the narrator in the full game referring to that. My guess is that the emperor was a planned character, but for a different role.
I agree with this. Daisy tried in her scenes to seduce to use the powers to do evil things. So I never trust her.
To be honest: I only met her during the first year of the EA. After this time I never used any Tadpole power so this scenes were never triggerd.
From my point of view Larian realised that the most players never used these powers because of the consequences. For me this is the reason
why using the tadpoles have no negative consequences in the game
