I think it would be more accurate to say every field has figured out how to minimize liability from harm to customers. Data collection makes companies money, and there's little liability involved in most cases if you aren't in the health sector, so they grab all the data whether their core business needs it or not. The health sector needs some data because sharing it is vitally important, and they've shown that it takes a massive amount of time and money and complexity to do it to any acceptable level.
If we had some way to accurately value our data and privacy, and laws that made it the property of the individual, we would see a change very quickly.
