A group that supports ethical non-monogamy sent an open letter to Meta on Thursday calling for Facebook to allow users to list more than one relationship status in their profiles.

The letter, which was initiated by the Organization for Polyamory and Ethical Non-monogamy, or OPEN, said that Facebook’s current policy is "arbitrary” and "exclusionary.” Signees included leaders of groups like the National Coalition for Sexual Freedom and the Center for Positive Sexuality.

A spokesperson for Meta said the company was reviewing the letter and noted that one of the statuses that users can choose on Facebook is "in an open relationship.” The change that the petitioners are asking for would allow them to list all of their romantic partners.
