they don’t know the language, you’re speakin
"What you said is amusing, hahaha! You don't know what language they [the developer] speak!"
Your comment was entirely useless; you're just assuming the developer is monolingual, and even if they are, online translation is easy and free, even if not fully accurate. Just because you don't speak their language doesn't mean they don't get to speak it.
(more literally and without rearranging words, "talk-yours is amusing, ha ha ha! you know-not languages-theirs.")
