Google Chrome is the browser I am using right now, and I used to use the Google Toolbar (only stopped when browsers introduced built-in search boxes).

Sorry I am not following you. Are you trying to say its okay to bundle/install 3rd party products that are considered good/acceptable? If so keep in mind humans have different tastes, what maybe considered good by you or me may not be by others. It is considered unethical to bundle programs since the days of Bonzi Buddy.
