An evaluation of good or bad an OS is for privacy should first and firemost focus on the actual OS, not the biggest contributer. It is an important point, and it would be way way more important if Android wasn’t open source. But it is, and it can easily be checked by security researchers. So saying Google bad (which I agree with ftr), and everything Google touches bad, would not only exclude you from many open source projects like linux, it would also not be a good aporoach to make a good, informed choice about your digital life.
Is this about how private and secure the actual usage of the actual OS is, or what?
