My laptop hasn't had stickers since a CTO asked why mine didn't have any stickers like the ones on the laptops of his cool cloud team. Personally I've found laptop stickers bad taste since then.

I'm personally not interested, but I also would never make fun of people expressing themselves.
On the other hand... mandatory fun, mandatory self-expression, any anything that takes something very personal and turns it into official or unofficial company policy makes me sick. I'm glad it's not too common here in Germany.
It's like HR forcing you to listen to punk songs because the company wants to promote a rebellious spirit as long as it's compatible with "disruption". It's also a bit like being asked "why are you so quiet" by someone who said everything worthwhile 5 minutes after getting out of bed but never stopped yapping.
