Because creating a new product is harder and more expensive than changing an existing one, even if it does destroy it.

Advertising, novel technical infrastructure, new branding, etc... all of this needs to be done for a new brand -- and then who knows if any one will come visit?

Or, you can just make whatever short-term changes to your existing successful product, juice the metric you're looking to juice, and (in theory) cashout before the long term repercussions take affect.
