Surely not if the material being summarized was free promotional material...

The issue wouldn't be in the summary, but in the presumption that it was a complete summary, which in turn would cause many people to decide that they now know everything there is to know about the subject, and see no reason to pursue it further.

Given that in this case it amounted to only a tiny fraction of the free materials, and was based on outdated models, that would be an inaccurate perception.

So, even though I made a joke about status, I actually do have an interest in ensuring that reviews of my work are accurately qualified.
