GitHub's replacement of master branch with main (2020)

By GitHub around Black Lives Matter, due to a possible ludicrous relationship with slavery of black people:For the love of God, the word "master" is much more general than black slavery. If you are going to ban it, you might as well ban the word "evil".

Several software projects followed the purge from their codebases, maybe GitHub followed someone else's lead, it's hard to say.

The words "whitelist" and "blacklist" were also targeted.
