Movable Type, the popular blogging software, has gone free/open, relicensing its code under the GPL, the gold standard for free licenses. We've used MT ever since we migrated away from Blogger (and Ben Trott, MT's co-founder, personally did the migration for us!) and it's great to see the company adopting best practices with its code-base. Even better is the company's statement about why they've adopted a free license: because they want to promote freedom.
Like many of us on the team, some of you have been waiting for this moment for years. For a business, an open source license affects boring things like how a product is created, updated, and distributed. But the open source movement has always been about something more important: Freedom. With a name like "Movable Type", we've always been keenly aware of the importance of freedom, as that name echoes both the birth of the printing press and the creation of independent media that an individual can control.
Our goal has always been to create the best blogging platform in the world and to put that power in the hands of as many people as possible.
