[docs-and-reports] Principle: Don't use Entropy (#4)

martinthomson has just created a new issue for https://github.com/patcg/docs-and-reports:

== Principle: Don't use Entropy ==
I've just been neck deep in looking at Topics and [the initial analysis](https://raw.githubusercontent.com/patcg-individual-drafts/topics/main/topics_analysis.pdf) there caused me a little discomfort.  It took me a while to realize what the problem was.

We often tend to think of privacy loss in different proposals in information theoretic terms.  This is useful, but it has its limits.

I've laid out my thinking on the topic in a longer blog posting that concludes that [entropy is a poor statistic to rely on for privacy analysis](https://lowentropy.net/posts/entropy-privacy/).
