(Playing devil's advocate marketing guy) Why would I allow you to see my product being website, web-based service or simply my advertising without the full experience? If I offer options to see a stripped down version then I am creating a consumer that will talk about the stripped down version and it will taint my brand. If you were to go to my site then when people ask you about it then I want you to tell them that your actions gave a non-optimal experience. (Non-optimal being my opinion of what I think you as a customer should be and not you a reasonable person should be)
