I recently joined a rapidly growing startup. In the past 3 months the development team has grown from 4 to 12. Until now they were very laissez-faire about what developers used to do their work. In fact one of the things I initially found attractive about the company is that most programmers used Linux, or whatever OS they felt best suited their efforts.
Now orders, without discussion, have come down that everyone is to switch to Eclipse. A fine editor. I prefer SublimeText2, but it's just my personal taste.
Just to be clear: we are a JS team using Backbone and Eclipse just isn't good at understanding Backbone code. This means that those on the team who use a /good/ IDE (PHP Storm), have to go back to doing a lot of search-find-oh-wait-where-was-I-three-steps-ago kind of things instead of just ctrl+clicking and using back/ forward - probably diminishing productivity by say 15% and enjoyment by 50%...
Is this a red flag? It seems capricious and unreasonably controlling to tell developers (non-MS) what IDE or tool-sets to use if they are already settled in and productive.
