Many companies have required sets of tools in order to do things like follow ops runbooks. Sure, you're a professional, but if you're following the team runbooks, you need to be doing it in exactly the prescribed way, meaning having your ssh access configured properly and the right version of python on your path, and any dependencies the shell scripts have, and rather than have you find and fix those one by one, a standard setup can save a lot of wasted time. Nobody's saying you can't use your own tools the way you want to, but you better be able to cope with having some team-specific tools and configs "shoved down your throat" or you really aren't a professional.
