Maybe the long-run solution is to make the coupling explicit: publicly post the value the company places on an account not being breached. (Ideally, this would work in tandem with some insurance policy that pays out for that amount, to validate that they really do so value it.)

Then, you can choose the provider with a high enough value to make you feel comfortable, in the understanding that higher-valued accounts will cost more.

This would work in many more contexts: The window sticker on my car can include the value they placed on passengers' lives when making cost-benefit trade offs.
