Most open source tool have the same thing that it feels like it's made by engineers. I think that's because it's true, most FOSS tools are made by engineers for engineers. Because most project start with someone needing something and then creating it and sharing it.

Chances of a programmer needing something and then making it is a lot higher, than an artist needing it and then making it as then there'd be a need to have the necessary skills to make the software. As someone not from CS field I've seen how much of redundant programs are present for CS related tasks while barely some exists for other fields because the overlap of programmer and that field is low specifically FOSS programmers. And a few programmers that field would have don't have the high level software development skills, so most open source tools made by them are "works on my machine, or works for this specific task" even though with less than 1% more effort they could have made a generalized tool.
