The original assertion was "If you care about privacy, don't use Android". A more nuanced and useful assertion would be this: If you don't trust a specific private company with your information, don't volunteer it to them. If you don't trust Apple/Google/Microsoft with all of your data, don't buy a device with a radio they have root access on and store all your data on it and carry it with you everywhere you go. This isn't Android-specific.
