Interesting but what should be of greater concern is how this collected data can be used and the fact that you can't have them delete it. It frustrates me when even very smart techies get caught up on data collection when we know advances in ML and behavioral psychology have made it so that these companies and governments can do some scary and downright disturbing things. For example: Sure, I don't like it when google plots on a map every place I travel to via location history. But of greater concern would be collection of gyroscope and other sensor data from my phone. Does <bigcorp> know how I walk,handle my phone and what other devices are usually near me? Can they use this and other seemingly innocuous data over time to recognize or infer behavioral patterns about me? Is any of the content I consume being filtered or customized based on this collected data? Can FB for example induce depression and cause n% of people to commit suicide? Can this data be used to manipulate employees to staying at or leaving a company,or applying for or declining a position? This is what concens me greatly,not whether or not google has a naked picture of me or if someone at FB has knowledge of my phone or text conversations. Sadly the public is completely clueless as to what is at stake -- it isn't just privacy.
