(Based on reading just one article, I've never seen or used the app) Seems like all the app did was serve as list of candidates, 225 electoral districts long, and a map from street address to electoral district.

Surely this can be trivially implemented as a website, in a matter of hours, no? It looks like the mistake Navalny's team made was trusting one method of distribution of information. Even worse, trusting a method with a central and corporate choke point.

That aside, I'm disgusted, but not surprised, at Google's actions.
