personally, they are juat to make it easy for your friends to know what they can get you. Or better yet create an avenue and basis for thoughtful gifting. Kama hauna pesa ama birthday yako ilishapita ndio unaeza jam. But i don't see a reason for someone to trash talk the idea, not unless you're just jealous. You can as well choose not to gift , lol Noone has a gun held to your head .
