This is deeply unfortunate. I know the folks at Maxmind fairly well, and they're good people. I'm quite sure this isn't what they wanted to do, and that they've pushed their lawyers to let them continue distributing this data as much as is possible, in a way that is as gentle as possible. I applaud them for their efforts; it is appreciated.

Unfortunately, it's also clear to me that this renders the Maxmind geoip databases non-free. I've filed bugs for the removal of the geoipupdate package from Debian main, and I believe the geoip-database maintainer has already terminated updates.
