> She readily confirmed that her JPMC laptop shipped to her via her company's address, and her outside management had informed her to "be careful with it."
That’s standard for company laptops. Nobody should be using the company laptop, which contains sensitive company information and access, to play games or whatever. Use it for work, then go use your personal devices for personal activities.
> Her JPMC management told her that she had to put it on a "normal network" after she got a dedicated LTE network for it that was literally only used by that device alone.
Common security requirement. Mobile connections tend to have frequently changing IPs. This creates problems with security software that tries to detect anomalous behavior.
> She was reprimanded for not turning on her webcam during meetings,
Having video on is a meeting requirement at some companies. It’s not unreasonable, even though some people dislike it. Video meetings are supposed to be analogs of meetings, where people talk face to face.
> She said "Sorry the camera just stopped working" and the next day a new machine arrived at her home, the address of which was not given to JPMC at any time.
I think you’re being fed exaggerations, or your friend doesn’t remember giving them her address. There’s no way a company would just guess an employee’s address and ship a $2,000 laptop there, hoping it arrived at the intended recipient.
