I don't really think it's actionable. It's like all those campaigns trying to steer behavior, pretty useless. Don't do drugs. Don't speed. Don't drink and drive. You can't just tell people something and expect it to happen. You need systems and guard rails in place.

Relying on maintainers to always do the right thing to ensure our security by telling them what to do is not the way.

It's not an attempt to steer behavior but rather intended as helpful advice. There are certainly cases of organizations disseminating "helpful advice" with the underhanded intent of steering behavior but that doesn't mean we should assume bad faith by default.

The advice is actionable because it is a concrete change that could be made. I believe it to be relevant to the context because someone in a position of authority who is badgered into accepting something would most likely benefit from reevaluating how he is interacting with the general public.
