Some hardware guys think software is easy. You can fix it in the field and most stuff is hacks in tcl, nothing difficult there. This leads to grossly inaccurate ideas about complexity and time in software development.
In the worst case, you get a model where the software guys aren't worth paying well because their stuff is easy, and somehow their stuff is always late and broken anyway so they can't be worth much.
Then noone can sell the hardware because it's worthless without the code and the company fails and it's all the fault of the software engineers who couldn't do the easy thing that, uh, the hardware guys also couldn't do.
