The same outcome is gonna happen either way, Google will say what their policy is, or people will spend time and bandwidth figuring out their policy. Either way, Google's policy becomes public.
Google could even come out and publish stuff about how to have good SEO, and end all those scammy SEO help sites. Even better, they could actively try to promote good things like less JS when possible and less ads and junk. It would help their brand image and make things better for end users. Win-win.
