To me this says nothing about how the author would respond to feedback given in a constructive tone. After reading this I’d still offer constructive feedback in a kind manner in a heartbeat. If, hypothetically, the author still sent me a rude response then I’d simply never contact them again for anything. The stakes are super low here.
