You can't control a system that you can't control, you can only influence it. If a company wants me to fix a technical problem with their system, I can't actually fix it unless I have the relevant access and control, such as SSH keys and username / passwords to web interfaces. I can suggest fixes, but I can't actually fix it. Plenty of things are simply too big for one person to do.
