I don’t think so. Working in tech with many busy people, I say “hop on a call”, but only in “let’s sync live, it’ll be faster” situations.
This stuck out to me as rude. I would never say that to someone on my team who expressed serious concerns, far less than this person quitting after years of dedication.
I would offer an apology, explanation, and follow up questions to understand more in public, then say I’m happy to set up time to talk privately if they would like to or feel more comfortable.
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".
