For what it is worth, this is absolutely not true and (regardless of what legal prescient may or may not imply) companies still sue people for such activities. While it has been shown several times that circumventing DRM does not explicitly run afowl with the DMCA, that does not mean you are not in the clear with the EULA of the software which leaves open an avenue for you to be sued in civil court for EULA violations.
If you go to court you may be able to defend yourself (depending on the circumstances of your DRM circumvention activities, the wording of the EULA, and the quality of the lawyers on each side), but it will still cost you a huge amount of time and money--a fact that is commonly exploited by litigative companies to punish people accused of such practices.
