I think Zeus actually comes across as whitewashed now compared to how he was in the pre-52 continuity. A lot of the things he's done have been glossed over or relatively easily forgiven. The fact that he basically forced an innocent woman to give birth to him doesn't seem to be treated with the severity that it should be. Hell, the Amazons who have spoken against him and 3 millenia long subjugation of women is portrayed as a villain whom we are meant to see as a straw feminist.
Rucka recognized that Zeus being on the throne brought more harm than good and rightfully had Diana and Athena boot him out.
