I don't know what led to the decision. The CEO had already built a very successful company on the same principles. The company where I worked had these same principles from day one. This also happened to be a start-up and not a megacorp. This was not in an anglophone country, so norms differ. I am from England for the record. Out of all of the companies where I have worked, this has been the most successful, and became successful the quickest. The IDE was IntelliJ-based. I have never before or since worked at a company that allowed "every man for himself" while managing to enforce the discipline required to maintain a uniform style guide, tests always passing and code review. It was nice to go over to a colleague's computer and see exactly the same code as I see on my own, and in the same environment. Everyone used the same debugger interface and same unit test interface, because everyone used the same IDE. They become more natural to use. People were able to refactor easily and maintain consistent naming standards, which is more difficult in Emacs, and especially in vim.
