Gods forbid I talk to people I work with, learn their preferences, and figure out the way we can accommodate each other. Sounds like such a waste of energy. It’s so much better if we all acquiesce to the preferences of some people neither of works with!
You can still talk to them about more important problems than placement of collons and closing bracket.
How does that work when hundreds of people are working on a project, with a few new people joining every week?
It boggles me that anyone would argue against standardization, or believe that “just get hundreds of people to agree today and tomorrow and every future day” is a better solution.
