It's worse than facebook because there's no one to have responsibility to be accountable. This ties in with your question about GDPR. While I'm not a lawyer, as far as I know it doesn't matter if you're a person or a company, if you're collecting data, it's something you can be liable for. So in a distributed system, all parties who maintain the data sources would be liable. I actually wonder how this works logistically in terms of storing account info on something like Ethereum.
