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.
Also, I don't know that I'm convinced that 'master' in this scenario is more descriptive than 'main'.
Moving back has additional costs, it doesn't simply undo the costs of moving forward.
For the record; I still use master branch for personal projects. But trying to impose it on anyone else is madman-levels of obsession that you might want to work out with a therapist. It simply does not matter to anyone with actually relevant priorities.
If it wasn't for muscle memory and my bash aliases, I'd be using main too. Get a life and stop bitching about default environment variables, it's a huge red-flag to employers.
