Even if you could somehow guarantee that there will never be hacks, I'd say that the very existence of this data is almost exclusively to the detriment of the "consumer". If, for example, one of the anti-abortion states wanted to subpoena Meta for location data of all of its residents who flew out of state to visit an abortion clinic, they easily could. If an insurance company wanted to partner with Google to see if you're getting your 10k steps every day, or speeding in your car, and adjust your rates accordingly, they easily could. We're living in a dogshit digital panopticon, and we need to take laws to reign this in extremely seriously.
