As an example, just off the top of my head, I bought a DRMed PDF copy of Spock's World, a Star Trek novel by Diane Duane. It used some particular form of DRM that was, at the time, integrated into Adobe Acrobat. It wouldn't work with non-Adobe readers (I use a Mac, and the Mac OS "Preview" app is a far better PDF reader than Adobe Reader) and, one day, Adobe decided to change how the DRM was implemented. Now I had to download and install a separate application which would periodically phone home to Adobe. I couldn't even read my book within Adobe Reader; I had to use this other Adobe app which had an even poorer interface.
Well, that
does sound like a pain, but I don't buy novels as pdfs, so that isn't much of an issue to me.
I have had something similar happen to me, though. I have a lot of IP that
I produced using certain programs. Some of those programs are now off the market, and even though the companies that created those programs still exist (*
coughMicrosoft
coughcough*), they didn't EVER produce translation programs for that older data to be used or accessible in the programs that supplanted the outdated software.
In some cases, that IP is locked up forever...unless I find an older machine (I, too, run Mac) with the right programs installed on it.
But being angered by that- or basing laws on such ocurrences- is like being ticked off that an 8-track tape of
Dark Side of the Moon can't be played in my 2008 Honda Accord.
IOW, my answer is either re-create the IP (in my situation) or re-purchase the IP in a friendlier (read: less danger of obsolescence) format. Books rock.
For another, suppose you have a small child, and he or she likes to watch DVDs. Bob the Builder, Dora, Spongebob, whatever. DVDs, of course, are easily damaged by small children. Wouldn't it be useful if you could make a copy of the DVD, keep the original locked up, and let your child watch the copy?
Sure, it would be useful, just like it would be useful for me to photocopy entire books so as not to endanger my originals. It sure would have helped me- I lost a collectible book to a puppy I owned, a book that was a childhood favorite of mine. It would have been awesome to have a "use copy" on hand and the original in some safe place, but instead of that, I wound up replacing the book with a non-collectible edition of it.
The law says that, despite the utility of duplication, there is a greater utility in protecting the right of IP holders to sell complete copies- even multiple copies- to consumers, rather than let the consumers duplicate things at will.
And I'm OK with that.
