Sometimes I end up failing them deliberately. I can't boycott them because they're often in the way of important sites. So my small, practically invisible protest is to never click more than 3 times. If you want me to pick out all the bicycles, you better have 3 or less. I'm only clicking 3.
I fully understand this isn't going to have any effect. Maybe if a million of us were doing it, it would. But it still makes me feel better.
