A few years ago the UK police carried out Operation Ore. It was a major operation targeting online child pornography. Some 7,272 British residents were added to a police database of people who paid to view child porn online. 4,283 homes were searched, 3,744 people were arrested, 1,451 were convicted. It was a major blow against pedophiles. Or at least, that was the theory. The US had a similar operation, Operation Avalanche.
There has been a lot of GPLv3 discussion on tech sites. Perhaps predictably, a lot of it has missed the point or miscategorized the changes. If you read the history of the Free Software Foundation and the GNU Public License, you discover that it all came about because Richard Stallman found himself having to use broken software that he wasn’t allowed to fix. The entire purpose of the GPL is to ensure that everyone who uses a piece of GPL-licensed software can change that software, use the changed version, and distribute it to other people.
