The problem is that it isn't just stickers on a piece of equipment.
A lot of these laptop stickers are either tech stacks (which are usually a form of advertising for a corporation), quasi-political messaging or outward political messaging.
I've partially explain this in my OP and other replies under this subject, but I and many other see them as a warning sign of things that are much more worrisome. I am naturally suspicious of any "corporate fun stuff" which is what a lot of this has turned into. That was accurately portrayed for what it is in office space with the "16 pieces of flair". Anyone who calls this out as suspicious will have someone like yourself saying "what is the problem? just a sticker".
