How do Siri, Google and Alexa respond to Black Lives Matter questions?

Apple's Siri and Google's voice assistant have both been updated to respond to questions about Black Lives Matter, and rebuff the sentiment behind the response "All Lives Matter." As spotted by sports blogger David Gardner, when asked "Do black lives matter?", Google's Assistant will respond: "Black Lives Matter. Black people deserve the same freedoms afforded to everyone in this country, and recognising the injustice they face is the first step towards fixing it." When asked "Do all lives matter", the Assistant will respond: "Saying'Black Lives Matter' doesn't mean that all lives don't. It means Black lives are at risk in ways others are not."
