Sorry, I've been ambiguous, but my statements arn't really in conflict.
There's no clause in the GPLv3 that says "you shall not implement DRM"
or "you must let users unlock DRM". Such a clause would make me very
happy, but it would go beyond what is strictly necessary to protect the
rights associated with free software. I guess most people who don't like
the GPLv3 are interpreting it this way.
What the GPLv3 *really* says, is that you must give your users a mean to
replace the GPLv3-covered portion of the software with a modified
version of it. This mean could come in the form of an authorization key.
To make a real-world, if Sugar were the only GPLv3 component in Fedora
11, the distributor would have to give the users a mean to run a
modified version of Sugar. Not X11 or the kernel, just Sugar. If Sugar
implemented some DRM in it, such DRM would be easily defeated. But if
the DRM were in the Read activity or in the kernel, the GPLv3 wouldn't
have anything to say on them.

DRM isn't an abstract idea! DRM is a mean for preventing users from
modifying a piece of software running on a computer. This is in conflict
with the very notion of Free Software.

Indeed, it's a political (or ethical) question: for many of us, Sugar
isn't Free Software just by accident. We wouldn't commit our time to
work on a proprietary educational platform sold by Apple or Microsoft.
If we wanted to see our work exploited for making children's iPads and
Kindles, then we'd better license everything under the BSD; this way
there wouldn't be any inconvenient obligations to fulfill for the
By updating to the GPLv3, we make a clear political statement that
commercial usage is ok, but our software must always remain free for
users to use, study, share *and* modify.
