The business model has been based on two premises:
For saving $5 you want to take a chance that a authority site(remember why you linked to it) disavows your link?
Don't forget that Google already rewards for outbound linking to good sites.
* linking out to good sites helps you
* when someone disavows your link it harms you
and BOTH are questionable at best. Linking out advantages have never been proven and disavowing harms have actually been denied by Google. Why bother?
