Google tells Australian Government it is considering withdrawing “completely”

I built a simple a plain CMS site for a school about three years ago. I made it load and render quickly, cache well, made sure all the headlines and text was on-message and... I think that's about it. The site ranks excellently.
There's nothing arbitrary or changing about any of that.
It's not about what Google says, it's about how others explain what Google says/Googlebot does. So Googlebot boosts, for example, sites that load and render quickly, and people explain "you should use X" and a few years later, "you should use Y". I do see how the change from X to Y is arbitrary.
