Almost every free iPhone app I install has a "enjoying our app? Rate it in the app store!" interstitial at some point in the user journey.
Is that "working to resist canvassed reviews"?
(I agree they should; I don't agree they are resisting it.)

I'll not also that soliciting a review of an app is not quite the same thing as organizing an effort to get a huge directional shift in reviews.
So instead you have the app asking things like this, or "can we send you notifications?", and so if you say no, it can ask later, and not trigger the OS interaction until just-in-time.
