I realized that I am a thief. :-(
Out Ministry of Culture have innovated its edict, that govern the additional charge for data storage media like CDs, DVDs, hard disks and similar. The reason is that everyone who buys it could store on them illegal copies of music or films and other works protected by Copyright Act. So they increased this charge so much that in some cases it is almost 10 % of the price.
I have to say that it is an example of very good lobbying of the organizations that take care of copyright fees.
But I am very sad, because I am a thief - when I buy a CD or DVD or even hard disk for data from my work.
