Windows App or Linux App that just happens to use HTML5 interface, but is installed and runs locally is a Windows or Linux Platform App. A website is necessarily a "Web Platform." Otherwise, you would have to argue that Google or Facebook primarily target Linux as their platform. Picture this. An alien lends on planet earth and asks you a question "What does this Google company do?" What do you answer: a. At Google they develop a search app that run on Linux? or b. At Google they develop the most popular WEB search engine.
