Updegrove vouches for "PJ" being a real person based ONLY on electronic correspondence

The only relevant disclosure here is the funding question. We don't know who funds project Pamela Jones. We also don't know who funds project Florian Mueller. Hypocrisy demands that one of those criticizes the other for their secrecy, and actually supports invasion of privacy of that other. When someone doesn't want to give up her privacy, that doesn't give you the right to take it from her forcefully.

Disclosures aside, what's really important here is actual contributions. One of them publishes truths and half-truths that help the open source community a great deal. The other publishes truths and half-truths to hinder the open source community. One wonders why this piece of work won't make any friends here.
