Original author here. I want to separate the technical work from the communication style. At one point I accidentally wrote Daniel's name as "Danielle." His entire response to one of my technical comments was simply, "That is not my name." I apologized, corrected the comment, and also made a point of acknowledging the quality of his work.
I think it was good that this exchange was later deleted, but it would have been better if the interaction had not gone in that direction in the first place. He appears to do strong technical work, and I do not want to diminish that. At the same time, some of his communication can come across as unnecessarily dismissive, confrontational, or unprofessional. That makes already difficult technical discussions harder than they need to be.
