I have one on my laptop that says "Fuck Your Algorithm." It's like a fine wine that gets more potent by the week, but it's about as political as my stickers get. The rest are just cool art I enjoy, usually from artists I meet at street fairs and whatnot, since it's an easy way to throw them a few supportive bucks without breaking my own wallet.

Saying they don't age well is pretty generalizing, given the variety of ways one can express themselves with stickers that aren't necessarily topical or political.

Theres better ways to choose stickers. Make them yourself and it's extremely unlikely you'll ever be at odds with that artist ;). Pretty art or ubiquitous fun phrases generally also don't really go bad, unless it's so tied to a specific artist that it represents them too.
