I suppose for me it is the thought that Autodesk will take an idea provided by me (or anyone else for that matter) that I have already developed, include a bastardized version of it in future releases, call them their own without giving fair and just compensation or acknowledgment of where the idea (or code) originated from. How many bits of recent code have you seen from Autodesk with their copyright attached, that have been merely re-incarnations of existing code, only re-arranged sufficiently to throw off the unsuspecting....and then they have the balls to charge us for it.... that is my grief...
I seldom spend "hours sloggin' out code" ... if it isn't something that I can do in a few minutes I don't bother unless I need it and cannot find it elsewhere. In reality the most productive code is those short little snippits that do one or two menial tasks.
