At work a lot of people have stickers on their laptops (myself included, but I don't put them on my personal one).

I've never _ever_ had anybody preach to me about some tech/event/company that they put a sticker of. My laptop is mine and I don't give a damn about what others think about it. I assume that this is the case of the vast majority of people who put stickers there.

This whole conversation reminds me of people complaining about vegans preaching.
