To limit myself to the topics, 1) The typical sole source of information on DRM is prior experience (Buying and seeing, or asking a previous buyer). I've never seen it described on the packaging of any software I've purchased in a box retail. 2) DRM (and money) are the two primary reasons for piracy. DRM effectively negates the reliability bonus from legal software since quite often the DRM will impact the user experience while using the software legally. The worst-case scenario for a mis-behaving DRM is that you need to wipe your hard-drive which is as bad as the worst-case scenario for downloading a piece of software with a hidden virus. 3) Yes, DRM systems have been implemented that require consumers to purchase the same content multiple times. This becomes a problem when it is not clearly laid out before the purchase and it disagrees with a reasonable person's expectations based on other copyrightable content such as a book or cd.
