In Sweden it's legal to both reverse engineer and modify a program for the purpose of making it run on your hardware. You are also legally allowed to backup your software and use the backup. Since Copy Protection stop the backup from working, you are thus allowed to reverse engineer and modify the copy protection to make it run on your hardware. Swedish law state nothing against distributing tools for this purpose.
Also Swedish law states that license agreements that deny theese rights make the license agreement void.
Ofcourse, the US have threatened the Swedish Government if they do not comply to their copyright laws, which forced the controversial May 2006
Police Raid against PirateBay. Ofcourse, it took less than a month before the website was up running again, faster than before. Distributing links is not illegal.
The act to strike based on US demands was illegal though.
