I hear what you've posted about competing with a $2t competitor but I'm not installing an extension and changing default search engine just to try your service out. Even going incognito or using another browser is more effort than reasonable to play around. Put a banner at the top requesting the change but blocking users? That's just unfriendly and puts me off from the start.
