In my experience, and in my feeling as someone reading such things, you need to tone-match. The resignation message was somewhat formal, structured and serious in tone. Replying in such an informal tone means that you are not taking things seriously, which is insulting. Even more so because that informal answer is public.
I'm tone-deaf by culture and by personality. I often make those kinds of mistakes. But a public resignation like this is a brightly flashing warning light saying: "this needs a serious formal answer".
Very much so, and I'm German ;)
