The top thing that would be high on my list is to fix the patent system for software. It's horribly behind the times, and inadequate for the software industry.

The larger problem with these types of behaviors and settlements is that the companies have very little incentive to actually fix privacy concerns. They can settle with cy pres awards, and their fines will get routed to charities they already support. Meaning, their annual donation is just a court ordered payment this year instead.
