It's just a word at the end of the day. To me "main" is literally a shorter word that means the same thing in my brain. It could be "trunk" or "release" or whatever else you'd like. "master" makes some people uneasy, so it seems like a simple solution to pick a different word.
The development community talked, informally settled on main, and here we are. Anecdotally it took me more time to write this than to switch most of my projects over. I use GitHub actions and a simple find/replace for a word not otherwise commonly used was the ticket.
I really don't care what other people use at the end of the day. Discussing version control and branching strategies drains my life away. If it is difficult to switch, don't, but if you start a new repo it is worth thinking about for a moment.
You seem like a delightful person to work with. I'm just saying be pragmatic and maybe try not to be a dick about it?
