I searched and there is at least one company: GoPro. See this article on Apple's attempt to invalidate RED's patent:
https://www.premiumbeat.com/blog/apple-vs-red/#:~:text=Essentially, Apple was asserting that,and shouldn't be upheld.
If the two companies were working on projects together, why the litigation? It’s likely that Apple wanted to dismantle the patent to avoid paying RED royalties. Companies like GoPro pay RED to use similar raw processing in their cameras.
So clearly they are letting companies license it. In the case of major camera companies, they will use their significant imaging patents to threaten them back and then settle for a cross-license. This will likely be the main reason RED is doing this -- to get protection from these very companies going after them.
This leaves companies without such portfolios such as DJI in which case, I say they would have to cough up and pay. That camera the youtuber talked about, can stand being $100 ore expensive to cover this patent. And RED is not going to get rich getting royalties for low volume products like that.
So all ugly but it is not what the youtuber says the situation really is.
