When you can choose the tools you want to work with and still complain about them, then yes, you are at fault. But when you are forced to use a set of really bad tools and there's not much you can do about it, it's legit to complain about them.
It's one thing being able to choose to use e.g. Emacs, git, and a language of your choice vs. working on a project that requires you to use an outdated version control system, a clunky IDE and more of that sort.
What on earth are you even talking about? Most people at Amazon I know use IntelliJ or vim, its their choice. The languages teams use are also that teams choice. The whole company uses git. I don't think you ever worked there...
