Painfully, it suggests "public vs private" hinges on encryption. The implication is that without encryption, your co-workers will see everything you do!
Public and private are distinct choices. Things can be private and unencrypted. Lack of encryption means lack of security in the event of a breach, it has nothing to do with choosing public vs private posts and web searches.
Works fine in my FF.
And for what it's worth, I think Apple should assist in revealing the contents of the phone if they can. I'm surprised people are defending Apple. My understanding is the request is about making the phone open to brute force attack, so it's not like encryption is under threat. It's poor password choice that's under threat. Apple does not need to compromise any other phone in doing this.
