This display of what appears to be computerised morality is especially surprising given that the device responds helpfully to requests for assistance finding prostitutes, Viagra, or a reliable drug dealer, not to mention a firing range.
It has duly sparked outrage in left-wing circles, where conspiracy theorists have accused Apple of a deliberate effort to provide assistance to the "life" lobby. After all, they note, Steve Jobs was the adopted illegitimate son of precisely the sort of young mother who might be tempted to seek an abortion.
The American Civil Liberties Union on Wednesday launched a petition calling for Apple to fix what it called the "troubling" state of affairs: "If Siri can tell us about Viagra, it should not provide bad or no information about contraceptives or abortion care."
Brandi Swindell, a prominent anti-abortion activist, said she was "thrilled" that the device is "embracing a position that promotes the dignity of women and upholds human rights in the womb".
Apple said the controversy was the result of an unfortunate software glitch, rather than a conspiracy.
"As we bring Siri from beta to a final product, we find places where we can do better and we will in the coming weeks," it said.
