So how can I stop using Equifax? Or at the very least how can I find banks or other agencies that don't use Equifax? Is there any way to stop them from hoarding all my data without my explicit consent?
Unfortunately, also, it's safe to assume that Experian and TransUnion operate just as badly as Equifax, so attempting to live an Equifax-free existence probably isn't particularly useful. If Equifax does suffer for this leak, actually, it's a relatively safe bet that they will take security more seriously so as to better protect their interests.
