But the whole thing raises another issue, which I will call "Corporate Trackback Considered Harmful". Kudos to them for leaving it all exposed there, but somehow I figure that's not what they were aiming for.
Edit: Trackback turned into an SSI (!) error for a while, but it's back now. Of the 74 unique trackback entries there, 51 are negative, two are positive, and the rest are either neutral or in a language I can't read.
(Me, I've never been that comfortable with MT's license, so I've avoided using it. I wonder if it's a vocal minority, or if they've really misjudged their customer base this time around.)
Edit: There's a bit of discussion on MT's new license at Metafilter.
