Looks like you have made a fairly accurate picture here.
Let me add a few more...

14) Fit fast blow fuses inside sealed double insulated appliances that will
fail from metal fatigue (why did they do this??? - it was sealed with
heatshrink onto one of the wires?!)

15) Make items as a collection of modules - example. Optics train in certain
models of projectors - instead of replacing just a hot mirror ($15 or so)
you have to replace the lot! (All optics and LCD screen etc as a module)
Now, try getting the poor serviceman to explain why the projector that cost
the customer $5000 costs $3000 to fix.
