Fun fact, there is only one group who decides what's a unix and what's not: https://www.opengroup.org/openbrand/register/

There is one group which owns an artificial, government-created construct: the trademark to "UNIX". That is far from the final word on what constitutes a Unix. The social meaning of words goes well beyond whoever owns a government-granted monopoly on them.

OpenGroup manages that social construct, the government stuff is just there to protect against misidentification and encroachment. The standards for Unix, Sockets, and LDAP were all transferred to OpenGroup to manage and they've done so.
