“Strive to be earth’s best employer” isn’t a leadership principle. - oh shit, it is now! My bad!

And “instruct managers to hide from employees when they're on a PIP”

This is not as clear cut. The document cited by Seattle times clearly states to not go into details of the Focus application, and instead go into how they can improve.

A quote: “Do not discuss Focus with employees. Instead, tell the employee that their performance is not meeting expectations, the specific areas where they need to improve, and offer feedback and support to help them improve.”
