From what I read, it is no clear to what extent a seizure or the bankruptcy of the service providers would impact the stakers. A 12% APR is a very promising profitability for a money that is otherwise frozen, but it has nothing to do compared to the loss of the 100% of the capital, if these problems happened.
If I'm wrong and there is no risk associated because Bitcoins are retrievable at any moment no matter what, then I will have to think it twice.
