'Make game of that which makes as much of thee' is some ancient wisdom. This sort of behavior by Google certainly does justify providing no more than a 12 hour window to Google to fix problems under responsible disclosure. Many in the industry are unhappy with Google only giving companies 90 days with Project Zero as they feel that large corporations should be given preferential and deferential treatment (they are people after all), but when it comes to app developers 12 hours is acceptable? I think not. Those who wish to set the rules must be willing to play by the same.
