Please report that. There's a bunch of operators on the #debian channel who regularly kick trolls and people who are not polite. The channel has had a pretty bad reputation in the past, but it's not really deserved anymore these days.

Not in my experience.

Absolutely wrong. Simple example: Debian's been providing a non-free archive, even though there have been several votes to remove it (all of them failed).

That particular bug, as it happens, has been fixed for squeeze. Debian now uses UUIDs rather than /dev/sd* entries to boot, by default, which does not have that problem.

Because Grub1 is horrible.

See http://bugs.debian.org/grub (the open bugreports against grub) and, especially, http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=239111#237 (a particularly telling example) if you don't believe me.

It's a bit of both, really

There's certainly a factor of 'because we can' in there, but it's also a matter of preference. I know plenty of people who prefer the FreeBSD userland, but I also know plenty of people (myself included) who've tried both the FreeBSD and GNU userlands and preferred the latter. Debian GNU/kFreeBSD is certainly not for people in the first group.

Also, since many of debian's postinst scripts assume a GNU userland (and are allowed to do so by policy), shipping the FreeBSD userland as default would not have helped the port.
