What's the purpose? The name is arbitrary, and in context they mean the same thing. So why do you care to change the default back?
"main" is better than "master" because it's shorter. The noxious politics are irrelevant at this point.
Your argument for changing it is not that the old way was better, but merely that it was the old way. But if dev culture has already shifted, then it is the new "old way". Any further change would be equally disruptive, even if it's to the "old old way".
That strikes me as equal-and-opposite political correctness. It's not done for a technological reason, but because you want to punish ideological opponents.
To answer your question: go ahead and say that. There are plenty of people who support your goal.
Use master as a branch name for your projects if you want, no one will stop you. But really consider if you believe "master" is a better name than "main" for the main branch of your repository. Like, imagine you're creating git today and need a default name for the main branch: is "master" the first name that comes to your mind? is it "main"? is it something else? This is the question you have to answer in good faith.
You are starting a flame war.
With everything going on in the world right now, why are you choosing this particular hill to die on? It doesn’t matter.
However, I do agree that the word “master” has a lot of different meanings that don’t have to do with slavery, so I don’t consider the word offensive by default. But I don’t think changing a default text label is worth getting on a soapbox about.
WRT github, you just skip the second line when adding your upstream origin.
If you mean the greater global consciousness... nobody cares. Main is 2 fewer letters to type, you'll sound like a madman advocating for anything else. It would be easier to bring back eight-space tabs or BSD coreutils. You should make your peace with it one way or another and find a productive hill to die on.
That ship has sailed and it's too late. Emotion triumphed over reasoning in May 2020 for Git.
That was the only time experimental pretrained language models were actually smarter than those who supported changing the default branch to main for unjustified reasons.
At least BlackHat® and the security industry resisted this nonsense.
My view is let the sleeping dog be. I see no compelling argument to change it other than spite.
While never personally bothered by then legacy terms, I can accept that they cause unease for some. On the other hand, I find resisting change or advocating to undo this change in the name of preserving history to be simply spiteful.
Our entire domain is defined by constant change and you swim needlessly against the current to lament that we do not go back to some prior state.
