For example DRM is present on most dvds and one can't watch dvds on Linux out of the box (for most distros). This can be bypassed by installing a library.
But you would never do this because this would be illegal...
Who cares about DVDs - Mozilla caved and added DRM (EME) to Firefox. These kinds of restrictions cut directly against freedom of speech and the press. This becomes yet another word game were you de jure have legal rights, but de facto do not because it is illegal to discuss the methods involved in actually exercising those rights.
/* before someone decides to repeat the propaganda that EME only applies to video (as if that is any better), remember the paranoid websites that try to disable the clipboard or show an image of text instead of just adding the text. "one frame video of text" is inevitable */
Thanks. I wanted to get a bit of clarity, at first I was thinking more along the line of VPN/Proxy to circumvent country restrictions or anonymize traffic, then cracking, but then I realized even this simple library example could mean a very high tariff.
