Perhaps that's one way to put it.  I would also put it by saying that
the DFSG must allow free distribution when aggregated with other
things, period, whatever character that other thing has, and
regardless of how big that other thing is.

We care about freeness.

We want to make *sure* that O'Reilly understands the license they are
in for, and not just implicitly.

That would solve this problem.  I would still want to be sure
*explicitly* that they understand this includes aggregations that
involve adding even a single page.
