I feel like this is unfortunately a semantic difference only - "cutesy" means different things to different people. Cutesy can just mean "informative but written in a friendly manner" to some people while as you and I understand it to mean "Jovial but unhelpful" - I think the user you're replying to is interpreting it in the first manner. A good example of a "good cutesy" error message might be Chrome's No Internet screen: "It looks like you don't have any internet, here are some ways you might be able to resolve it... but also here's a little dinosaur jumping game to pass the time".
