We are turning into a nation of wimps and wusses by the idiots in government who insist there's a terrorist/hacker/exploit/fill in the blank threat under the bed, around the corner, waiting for the flight/bus/train/subway you're about to get on, bugging your phone/home/workspace, tracking your car, etc.
Excuse me, but those very government officials have no clue about the internets. Most of them probably believe Al Gore invented it. And their complete lack of knowledge is the best reason for them to leave their grubby little mitts and their increasingly ill-informed, poorly-intended laws as far away as possible.
An IP address is not a person, in the US. How that can be conveyed to the idiots in the UK government, where justice seems to be a slippery construct (nailing jello to a tree, anyone?) is another matter entirely.
That was a legitimate piece of software intended for making a backup copy of a DVD so the real one wouldn't get annihilated by the kids the first time out of the box. That got shot down pretty fast by MPAA, although I still have a copy...
Anyway, Judge Posner's ruling applies to an ephemeral copy of a work that is held temporarily in a buffer. No copyright infringement on the part of the viewer here. Somewhat like borrowing a DVD from a public library and watching it, or like the old Borland software license (install on as many computers as you want, but you can only use it on one ccomputer at a time).
Trollhattan is a real town in Sweden. SAAB had a car factory there back when they built cars. I had the bumper sticker "Made by trolls in Trollhattan". That doesn't excuse the epic humor failures, though.
