To each their own. Sure my coworkers complain about this or that annoyance in WebStorm or whatever that they can't customize or fix, but then they never lost the better half of a day to ~/.vimrc so...
I can see it both ways. I'll choose customization, but I wouldn't fault someone for expecting a good out-of-box setup.
Most of the development tools I use on a regular basis tend to be extremely customizable, and I regard that as a Good Thing.
