I'm not entirely sure if I understand your question... "Purchasing views" from websites is bad, and it is against YouTube's ToS.
However, embedding videos on a website, such as a blog, for example, and having people view the videos from there is a perfectly legitimate traffic source. YouTube prefers to keep traffic within YouTube, so I'm not sure how outside views affect the video's search ranking within YouTube, but I don't think the algorithm will pull a video from its search rankings if it's getting a lot of outside traffic.
