Sure and if you know what you are doing and accept the risks its a fine thing to do, but it isn't a good idea to actually encourage that behavior in new users.

Sure and if you know what you are doing and accept the risks its a fine thing to do, but it isn't a good idea to actually encourage that behavior in new users. The argument I have seen here that it is the way new users want to install software, so that should be the way to do it. But encouraging users towards bad behavior, because you don't want to force them to learn anything new, is completely unhelpful. If the user doesn't accept that he has to learn the new Operating System and has to find alternatives to his software (like ditching chrome for chromium) he will never be happy.
