Movable Type licensing

Six Apart has announced a new, very pricey, licensing scheme for Movable Type. There's still a free version that seems like it should meet most individual bloggers' needs but the Trackback comments appear to be almost entirely negative. I wouldn't be suprised if Six Apart has to significantly modify the terms to prevent a mass exodus. I'll be switching to WordPress this weekend since I've been looking for an open source tool anyway.
