Checklist §2.3: "If a part of an article is not available in the Instant View format, an IV page must not be generated. [...] Mark any unsupported essential content using the @unsupported function." (https://instantview.telegram.org/checklist#2-3-pages-featuring-content-unsupported-in-the-iv-format)

Checklist §6.8.2: Videos from unsupported players -- "Otherwise, mark the object with the @unsupported function."

The article text by itself is insufficient to cover the lack of the video. This is especially true for articles which reference the video. It is confusing to the end-user.
