In 2006 the government of China suddenly blocked WordPress.com from their country, thus cutting off 25% of their traffic. WordPress founder Matt Mullenweg soon learned China would unblock the blogs if WordPress would block specific words and phrases, as well as giving info on users to the government.
Mullenweg refused. Too many CEOs of other companies have cravenly done the opposite. Good for him.
Not that I wasn’t already using them because their product kicks ass, but even still, WordPress just got themselves a customer for life.
