Six Apart took another crack at Movable Type pricing. It’s a lot simpler. For non-commercial use, you can pay $69.95 to get up to five authors and unlimited blogs, or you can pay $99.95 to get unlimited authors and unlimited blogs. They’ve also fixed most of the license issues.
For me, this license and this pricing scheme work. I’ll be upgrading sometime soonish, most likely. I expect there are still people for whom it won’t work, and I think that’s a perfectly rational decision too.
