All this fake stuff comes down to is that those who use it seem to feel less watchable or listenable without it. It's like people who use makeup. Why they use it is out of a either a form of insecurity or as a form, self flattery, or as an enhancement/artistic form of expression. It's one thing to be open about the tools you use and another to lie. This is like the models who obviously have had a ton of plastic surgery done and swear they haven't. If you took it all away then they would feel people think they aren't good enough or sound bad live. Maybe that is true, maybe not. Fact is that either way it's not entirely live once that method has been implemented. Whether the observer cares or not is up to them, but whether they know if they're being lied to or not is another thing altogether.
