You're making very strong statements that aren't backed by empirical evidence. All I can say is that I see that successful chat apps for 'normal people' seem to have converged on something that isn't WYSIWIG, and it's probably not an accident. P.S. Asking users what they want probably isn't the best idea. See "Homer's car" for a humorous take on this issue.
