I think only pirates have a reason to fear digital rights management
You don't have to be a pirate to be limited to what you can do with stuff you legally own. With DRM, no backup copies of a DVD so you can keep the original safely boxed up out of harms way (anyone with toddlers would agree that's a good idea). Thanks to DRM, in many cases you cannot run a computer game directly from a disc image file, so you get to haul your CD's along with your laptop whereever you go. Thanks to DRM, your legally bought 'protected' music files become worthless if your computer crashes and you need to reinstall the OS. Thanks to DRM you 'cannot' copy certain media, while the music industry still holds up their hand and collects a copy fee on any blank media sold in many countries.
More worrysome: The whole direction of 'trusted computing' that things are headed to can have major impacts for you and me -- if things go the way the big companies want them to (and they probably will -- after all, they have enough backing from Big Business), everything will need to be 'trusted' at some point. Nice for Microsoft, but the final nail in the coffin of small, casual developers who don't have money to go through the process of having their (free!) programs certified just so windows will trust them and allow them to run.
DRM is a very slippery slope, and is just a major inconvenience for legitimate customers. Something is very wrong when a pirate gets a *beter* user experience than a legitimate buyer.
