Carl Levin actually said...

Companies today have little incentive to disclose their role or knowledge of a security event, leaving consumers vulnerable and unprotected ...

In other words, if you opt out, those companies can no longer collect information for interest-based advertising for you?

If we cannot vouch for who the advertise is, we should not accept the ads in the first place.

Is there any reason why you cannot ask consumers whether or not they prefer an opt-in or an opt-out approach?
