Over half of all humankind uses an Android smartphone. Google does not own your phone. You own your phone. You have the right to decide who to trust, and where you can get your software from.

I’m glad to see some initiatives being brought open with this, such as keepandroidopen.org. Although alternative mobile operating systems exists, but with the domination of iOS and Android—especially for the required banking and government apps—make it hard to daily drive such systems. Using two phones, one with stock ROM and one with custom ROM without Gapps, is a solution, but it can be a chore.
