I was partly responding to my own irritation with the underlying premise of the article. If Tor is being used maliciously to deliver or receive an encrypted payload on your computer or network, it isn't a problem caused by Tor. Furthermore, Tor has an enormous social benefit.

In other words, my first reaction was that it is harmful to attack the technology, but realized that is a silly argument for obscurity. Publishing a vulnerability, and more people publicly searching for vulnerabilities is a good thing, since authoritarian actors will just exploit what they find without any disclosure.
