This is pretty far from how the other open communities react.
Not really. Difficult bugs take time to address. All hardware bugs are difficult.
For example, this arduino-related gcc issue took 7 months for the compiler gurus to say that they weren't going to fix it.:
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=38342
(and gcc is a pretty shining example of open-source-software. There's a LOT of stuff out there written by students, released on a lark, and essentially abandoned when they graduated and got a real job. Shucks, "winavr", the packaging of gcc and related tools for AVR development on windows, was nearly abandoned.)
