You can have privacy and many of these things. You may be interested in homomorphic encryption or the weaker version differential privacy. There are such things as zero knowledge proofs.
But I think it is far easier to have these technologies without doing the encrypted aspects or protecting privacy. Then it is more a "never let a tragedy go to waste" situation. Paved with good intentions, right? This will always happen though as we rush and are unable to do things the right way. Often the right way can take the same amount of time but generally appears to take longer and that is enough, even if the wrong way actually takes longer. Because it also matters at what resolution we're concerned with.
So I'm saying it is mostly stupidity, not evil. Though evil loves and leverages stupidity.
