| The DVD CSS mess
I support the rights of myself and all individuals to take apart
and/or reverse-engineer anything we have paid for. We are free to
explore and understand the things in our world. It's called progress.
Do not sell me a locked box and expect me not to open it. If automakers
suddenly started selling cars with locked hoods that only the manufacturers
could open consumers would be outraged. This is the same thing.
The DVD and deCSS wars are not about pirating DVDs. Besides the
fact that DVDs can and are right now being duplicated without breaking
the CSS encryption, the people who first cracked the CSS code did
so only to watch movies on their Linux computers where no commercial
players were available.
That piracy is wrong goes without saying. I favor the type of solution
where media is cheap enough where those licensing the content make
their fortunes on volume, not overpriced, heavily pirated products.
DVD piracy is almost nonexistent because DVDs are generally priced
reasonably. Often, new release DVDs can be purchased for less than
the average cost of two movie tickets. This is how it should be.
Morality aside, consumers will buy DVDs rather than pirate them
if the cost of the DVD is less than the trouble of piracy.

This is a mirrored copy of the analysis of the encryption routines
in the CSS system. Aside from the english parts and the astute conclusions,
I don't pretend to understand any of this document:

DeCSS source code
For a short time last year, the deCSS source was posted to Download.com,
there were 60,000+ downloads before noon. It was later removed.
The source is also available on T-shirts from Copyleft.
I haven't used these files and don't know what the difference between
