I don't get it, are the government contracts somehow contingent on them oppressing users and stifling open source?
>we are now in an age where users can create their own apps to do whatever they want within a few hours, sothis risks their Google Play Store profits
If that's the reason, they're doing a pretty poor job, since it's trivially bypassable by running "adb install".
The day probably would come where Google does open sourcing just for namesake that too for insignificant piece of software. And other companies will follow suite. There would be time where everything thing will locked up and monitored.
I am so thankful that the PC revolution happened way before app stores and there was a period of open source culture and open formats etc.
