content: While it would be nice to prevent the potential misuse of data after you've shared it, that's not the problem PODs aim to solve. I believe the intention is to give users more control over their data-at-rest. With centralized hosting, you have no way of verifying how your data is stored or with whom it's shared; you just have to accept their ToS at face value. Spooks need only tap into a central datacenter to gain access to all users' data. Decentralized hosting mitigates these problems.
