The defamation angle is not interesting.

They are pretty clear they will go after them for torturous interference, unfair competition, etc.

California's UCL is much broader than you may think here - it is consistently interpreted very broadly by california courts, and has fairly low requirements (IE fraudulent business practices under the UCL do not have meet the same requirements as fraud)

One fun thing is a lot of state consumer protection laws have a punitive damages component.

The diminished standard of intent and the fact that a mere advertisement can trigger liability in some states makes UCL/CFA extremely powerful in some cases.
