Airbnb has launched an equality supporting campaign in Australia. The multi-billion-pound company is asking Australians to wear a black ring until same-sex marriage is legal in the country, the ring is incomplete symbolizing a gap in equality. Airbnb has promised it will not profit from selling the rings, and has received backing from Google for the campaign, called Until We Belong. Demand was higher than the campaigners expected and all the rings are sold out already. Brian Chesky, Airbnb chief executive, said the new campaign, which was created in collaboration with equal marriage advocacy group the Equality Campaign, was about “openness and belonging.” He added: “This is an opportunity for people to show their support for marriage equality – not just those within the LGBTI community, but for anyone to make their support for a brother, sister, parent or friend of a loved one known.” The video created for the campaign features a gay couple talking about the “disconnect” in the ring, saying it represents “how we might view ourselves as well, from the community.” Activists then pledge to wear the ring until their sister, son, uncle, mate, cousin, mother and brother can get married.
