Wanting your documents and writings to not be fully accessible to CCP intelligence services....is not exactly "heightened security requirements" to me.

This device is basically completely un-trustable.

Leaking information related to financial stuff, research, invention, product design, or legal/government work. For a publicly traded company any manner of documents / notes on a device like this could spell trouble.

Plus, if they're able to identify something you don't want others to know, they have leverage on you.
