So the “available for download” part is at the very least bad phrasing and at worst potentially misleading. Obviously anything you pay for and license is “available for download”, but if it’s not free to use then what’s the point? If anything it should simply state that the effects are “available”, as in they are now available for purchase.

Also, isn’t the BBC one of many publicly funded media outlets? It should at the very least be free to use for those who pay to keep the service alive, and ideally completely freely licensed as I think any public work should be.
