I think they even went as far as banning it on hardwares Edit https://en.wikipedia.org/wiki/Master/slave_(technology)#Terminology_concerns Terminology concerns In 2003, the County of Los Angeles in California asked that manufacturers, suppliers and contractors stop using "master" and "slave" terminology on products; the county made this request "based on the cultural diversity and sensitivity of Los Angeles County".[9][10] Following outcries about the request, the County of Los Angeles issued a statement saying that the decision was "nothing more than a request".[9] Following the controversy, Global Language Monitor found the term "master/slave" to be the most egregious example of political incorrectness in 2004, and named it the most politically incorrect term of that year.[11] In 2018, Python replaced the term, after a heated debate. Many developers in the discussion on whether to make the replacement agreed that the term "slave" should be replaced while "master" was not offensive, while others argued that changing "slave" was also unnecessary. There was similarly contentious debate among developers when Django and Drupal (in 2014) and Redis (in 2017) replaced the term.[12] The Black Lives Matter movement sparked that discussion again in 2020. Some have argued that the change is superficial and that companies should make real change to support the black community.[13][5] See also similar concerns regarding the technology term "Blacklist". In 2020, the Open Compute Project published Terminology Guidelines for Inclusion and Openness which recommends general terminology and commonly used pinout and signal names which to deprecate and suggested replacement terminology.[14]
