A short excerpt of that mail:

The Mozilla Public License (MPL) is not DFSG free:

1. It does not allow derived works to be distributed under the same terms as
the original software (DFSG #3).

2. It requires distributors to retroactively notify recipients about third-party
legal problems with the software (Dissident test).

3. It restricts court venue, permitting licensors to harass licensees and
effectively revoke the license. (Tentacles of Evil test)
