Google [1] and Ask [2] isn't better either, they are offered with most updates of Adobe Flash and Java. Guess everyone will sneak something in if given the opportunity.

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.

I think Bing is more willing to spend money to get traffic. You can easily get $5 a month in Amazon credit from their rewards program just by using Bing. They have a few other interesting promotions, such as starbucks cards and XBox Live Gold membership. But I'm sure this is costing them a decent amount of money.

Why Bing? Because Microsoft is desperate enough for market share to buy traffic through affiliate marketing.

I guess you never had random apps offer to install Google Chrome and make it default browser (which I consider being spyware wrt non-tech-literate users).
