Android is an awesome platform and Google provides an important infrastructure on top of it to make everyone’s experience even more pleasurable.
I do not generally subscribe to the philosophy that just because you moved from Google’s infrastructure you are safer on your small time VPS. At the end of the day they all follow the law of the land. They comply with the same government.
One of the major benefits of using a big time company is that they have immense amount of money to hire best people in the world to both keep your data safe and backed up for rainy day.
I would like to live in a world where both Google and an indie developer is on the same level playing field.
