Tech is big enough and experienced people have enough hiring power that I've never heard of anyone skilled that couldn't get another job even if they were as asshole, much less gave honest feedback. I consider it part of my integrity that I try to bring to every job to give honest and direct criticism about things I found lacking, especially if I'm leaving because of those lacks. Perhaps they fix them, perhaps they don't, perhaps it helps other people on the team, but I can't imagine an actual downside outside of highly specialized niches where one could actually be cut out of further opportunities even with competitors
