I would like a filter to allow the text displayed on the link to be changed.

Use Case

For custom video providers, or for self-hosted videos, I'd like to be able to change this so it doesn't say "the original site" but instead get_bloginfo( 'name' ).

I'd also like to be able to change the "View on" prefix text, to "Watch this video on",

This can be done by sending the complete string (prefix + $provider) to a filter before adding it to the component.

You should be able to filter the generic embed component's JSON and substitute the text for whatever you wish using the apple_news_embed_generic_json filter.
