I also see nothing wrong with brigading, if you are an actual legitimate user of an app and are unhappy with it.
Businesses solicit positive reviews all the time.
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.
