What habit is being changed? Aren't the default names defined by the git software? If so just change the software and push, but what habit was changed? Doesn't change current repos but why exactly is that the problem? If you are trying to set a precedent, i.e. stop the bleeding, then a git update would work just fine. Is it assuming that 'master' should be the default? The name 'master' doesn't have any special significance to the software interacting with it as the branch name is just an identifier. The term 'master' in the Comp. Sci. sense is jargon meaning basically 'the source of truth' not 'one that controls the wills of others'. The only habit I see being altered is to be readily conditioned to accept without question the dictates of political interest groups and large corporations as to what terminology is acceptable. Who defined these groups as the rightful arbitrators of this jargon?

"So, next time you are annoyed that you have to fix a script or you accidentally type master when you needed to type main, please just take a deep breath, change the name, and remember to reflect upon whether you have are subconscious habits or biases that work against diversity in tech."

In order words, the next time you have the urge to think critically about what you are allowed to type and who is forcing that decision upon you take a deep breath, shallow your skepticism, and reflect upon whether you have been indoctrinated enough into the new political Zeitgeist.
