Missing the point
Isn't everyone looking at the technology involved and looking for regulation or protection of interests of this stuff? Take deepfakes out of the equation for now. I guess the concern is "But they are so misleading, or will be in future and that's a worry" - But why is it a worry?
"Fake news" has grown a lot recently because of the prevelance of social media, but as far as I'm aware, even before the 90s we learned at school how to find and trust primary sources before jumping to "OMG THEY SAID THIS".
Doctoring videos has been around as long as videos. I don't even trust newspapers given their funding sources and interests of their owners.
Surely it's up to the consumer/viewer to say "I've seen a video showing X said Y" and not "X said Y". Isn't "don't believe what you see on the internet" a thing still too?
