The comment I replied to specifically brought the strfry function up. So does the web page explaining why Debian has switched to eglibc. Different people have at multiple times stated that this is one of the important reasons for switching away from glibc, and I was making a direct response to one of them. Please explain to me how I am making a strawman argument.
Other then that, I agree with your comment. Drepper is by default terse to the point of approaching continuous rudeness. When people try to waste his time, he will flame them. He even perceives people as wasting his time when they are actually making valid questions sometimes. He is hard to work with. Glibc would be better of if he wasn't.
But much like Theo, Drepper is an exceptional project leader when it comes to technical aspects. The most relevant question is, would glibc be better of without him? Would it be better if an average coder with good people skills was managing the project? My guess would be no, that all the combined lost contributions from other people are smaller in value than his contributions to Glibc. Same thing with Theo. On the other hand, my guess would be that Jörg Shilling and the XFree86-people fall on the other side of that line. But that's just me guessing.
