Make stickers and go put them on the units at the store. Send Bosch a picture of how you've improved their labeling along with a nice note indicating that you'll do it again if they don't change their ways.
That'd probably get you banned from the store if they find you doing that and at best, it's only going to get the message out to a few customers until the store staff remove the stickers.
Jeff's using his internet fame to reach far more people. I previously thought that Bosch were a good brand (only had a blender and a temperature controlled kettle from them though), but now will avoid them.
Ok, but not all of us have internet fame. I've found that my "here's where to pirate this textbook" stickers are not typically removed. Maybe sellers of dishwashers are more diligent, who knows.
Fair enough. I do enjoy seeing various subversive stickers put on lampposts etc. Maybe complaining on the internet and putting stickers would be a better tactic, but placing stickers probably takes more effort.
