If you're fast enough at typing, you can type in chat to alert other people to stuff (at least in normal content). Should we do something about this too? After all, it modifies gameplay too. Or are you gonna say that since it's using something built in the game, it's ok? I don't think what people here are discussing is about modifying the gameplay itself but about some people having an advantage over others and relying on something that's not a human to do part of their work for them. VC isn't harmful and anyone can use it (PS players included), unlike 3rd party programs.
