Moving it over there. Full-quoting because of this.
Summary: I don't believe this is a free software licence, failing at
least DFSG 3, 4, and 9. It may additionaly fail DFSG 6. Due to the
failure of DFSG 9, I doubt this can even go in non-free.

Not sure what they're thinking, as this definitely isn't GPL-compatible.

However, I don't see anything allowing us to distribute binaries built
from patched sources, thus this seems to fail DFSG 4 ("[t]he license

I'm uncomfortable with this, but considering the other problems I can
punt on deciding :-D

Fails DFSG 3.

Fails DFSG 3 and 9 (restriction in this case is "may not be distributed
alongside server software"); also possibly 6.

Not sure how this affects DFSG freeness. I can't think of a single free
license we've seen on -legal with similar provisions.
