I did that recently. I had been developing some code for a few months, committing to a local repo, and I finally decided to upload it to GitHub. The local branch was named "master" because that is Git's default, but GitHub decided it should be "main", so the first thing I did after creating the repo was to revert it to "master".

Fuck virtue signalling and Twitter keyboard warriors. My parents grew up under an oppressive ultra-catholic dictatorship where they had to pretend to be "good" Christians, and I for sure don't want society to go the same way again.
