If the modification this guy made actually made the copy WORSE, then the reaction is completely understandable. I think the problem is on how do you know what is actually best? This is a problem for developers as well. "you refactored my code into some unreadable crap" - "I made it more clear and DRY" Lots of code (and copy) are highly subjective, like when to use a design pattern or when/if to break the Single responsibility principle etc. It's easier if you have a tight team that have worked together for a long time and get a long fine. However, it's also good with different views in order to actually get the best solution in place. How do you handle these kind of problems in a good constructive way?
