If Google want secure encoders and decoders, then they can donate money or patches. Since they don't, the clearly don't actually care all that much, or are just mooching of volunteers' goodwill.

The disadvantage in speed when using Rust is pretty obvious.[1] When it comes to video encoding and decoding, I and FFmpeg care a lot more about speed than memory safety. So those reasons have been considered and largely discounted.
