Oof. I don't like this decision, and surprised to see the breadth of agreement from the Court. When you grant a person access to a system (digital or physical), it's for a specific purpose. Violating that purpose should be a criminal act. If I give a plumber my house key to come in and fix my sink, and he goes and he opens up my computer and looks at my files, that should be a crime. If I grant a Geek Squadder access to my computer to get a virus off my computer, and he looks at my private photos except to the extent necessary to do the job I hired him to do, that should be a crime.
One could always say "Congress can remedy this with legislation" but that body has become fully dysfunctional so we all know that won't happen.
