That's like saying a mass murder just killed 10 people in a single go so it should be 'just one thing' in court. Each individual act is a separate 'crime'.
This even includes some bad police work. Because since the developer didn't post a single app of this type after the initial suspension google could have easily identified all apps and found them all and notified the developer that all apps must be dealt with.
This would be akin to the police having 10 open murders with the same exact weapon, charging the assailant with one and not looking for any other open murders on file.
