SD cards (and other memories) have processors whose programs can be changed.

TED is based on the assumption that all we need is a clever new idea.

Al Jazeera correspondents in Egypt have been arrested for interviewing members of the Muslim Brotherhood.

When a government accuses someone of publishing "false news", or says it is illegal to interview someone because he's been declared a terrorist (or even convicted in a fair trial of a terrorist act), that's manifest tyranny.

The UK censorship filter blocks more than porn. It blocks access to sex education sites, even help-lines.

It also blocks many free software sites, and even amnesty.org.

These schemes always make mistakes, and this is proof that that continues to happen. But let's not be distracted by the mistakes. Even if they could fix all the mistakes, which they can't, that would not make censorship acceptable. Fixing 90% of the mistakes, which maybe they could do, would not make it acceptable either. Down with censorship and the tyrannical rulers that impose it!
