That global market includes the US, which is a substantial part of GitHub's revenue.
This thread started as madsmith's valid comment that "that language is dynamic and the meaning of words is the meanings we currently associate to them" - how do we determine what meanings are associated with a given term? All indications are that it has a US origin, which provides the appropriate interpretation.
What is "the problem" and what should GitHub do to address the problem?
If the problem US-centric, and you think the US-only issues can be ignored because GitHub caters to a global market, then isn't your logic that GitHub should do nothing?
