Perens was fairly dictatorial. He also viewed the open source thing as more of a marketing tool than an ethos. That rubbed a lot of people in the groups the wrong way. He also was an effective project manager. Little column a, little column b.
I’m also interested by any source about that. I’m reading a lot about open source history and can’t find anything about that story (which seems quite important for those who want to understand Debian history)
