> There's no reason for third parties to give up what they view as lucrative personal data on you to have it stored elsewhere. The status quo is profitable for them, and this is an unproven system with no market share - so they have a handy excuse not to cater for it.
There are a lot of third parties, and for many of them, keeping your data is not their expertise nor business model, and neither is the protection of it. There's plenty of personal data sloshing around in badly protected databases of companies that need to use it for their primary competence, and for whom new legislation is increasingly turning it into a liability. Being able to use it without needing to be responsible for it can still be an attractive proposition.

I look forward to the day we get there. From my own experience, companies aren't taking those responsibilities nearly seriously enough yet - although heftier punishments under new laws will hopefully change that.
