I got the reference. Seems like it worked out quite nicely for the government/court though, given that deCSS isn't much use printed on a t-shirt, compared to in a binary on a computer?
you can't share the compiled binary, but you can share a shirt. if you have the shirt, you can compile on your own. the t-shirt became the sharing network
That’s the thing about speech: It’s very hard for governments to physically prevent it, but attaching consequences to making use of that capability usually works just as well.
