@Mer__edith I worked for SCO back in the late 80s and early 90s, and a (now) extremely well known open source evangelist was trying to get the word out about open source, including getting a major project he was running in use on SCO Unix.
There was an incompatibility between that project and the package that SCO already shipped that did the same task. But, in theory both packages could be used at the same time if the incompatibility was resolved.
I wanted to try the new open source tool, so I emailed the maintainer (long before we used that word), and proceeded to have a brief and downright shitty exchange that didn't end up solving the compatibility problem.
After that I decided to avoid that individual from that day on, which I have. That was my introduction to FOSS culture.
I should point out that before Internet and search engines were in widespread use, most strangers I interacted with online assumed from my name I was a woman. The ick factor was high at times. Not sure if that influenced that crappy interaction outlined above, but later news about that individual makes me think so.
