I do. I edited before posting up my fanfics on archives etc back in those days and I edit before I submit my pro work now. I'll usually have done at least some editing before early drafts go to beta readers. I've sometimes had critique on first draft work, but always with the intention of doing my own editing that the critique feedback would be only part of, not the whole thing. (That's usually big picture feedback anyway, not line edits.)
I don't say that means it doesn't need editing some more after it's submitted. That's the case for almost everyone. I go as far as I can on my own, and with my beta readers.
That doesn't mean I can claim that every writer edits, because I see people who deal with the slush pile say that many things they see are not edited. Maybe that adds up to "most writers", but I'll bet it doesn't mean most published writers. But to say that "no writers really do edit before they submit for criticism" is clearly wrong.
