Yes, you are. You may not want to do that (and instead do it per user), but that's what you asked the computer to do.
There's nothing stopping you from doing what you like in your user space, but similarly it's no-one else's fault if because of a system change your stuff broke (and hence because sysadmins don't want to do more than they need to, managing things globally is what the expect and support).
