Chrome could change their extension policies and put a severe damper on the business overnight. Consumers would have the option to use a different browser, but it's likely that many of the Honey users did not affirmatively register for an account and are using the extension passively. Enough of a relationship exists between Paypal and Google, and the Honey extension doesn't particularly bother Google to begin with, that this is probably an acceptable risk for them. But it was notable to me that such a healthy premium was paid for a business built almost entirely on a browser platform.
